Prior to June 2026, Immigration, Refugees and Citizenship Canada (IRCC) didn’t describe acceptable documentation for Canadian ancestors who were born in the 1800s or earlier. Their web page “Apply for a Canadian citizenship certificate: How to apply” was silent on this issue.

An archived version of the page is available here:

https://web.archive.org/web/20260614134240/https://www.canada.ca/en/immigration-refugees-citizenship/services/canadian-citizenship/proof-citizenship/apply.html#apply-paper

As a result, genealogists could only find and supply documents that provided evidence of birth based on genealogical best practice. See, for example, When Your Ancestor Has No Birth Certificate: Genealogical Proof and Canadian Citizenship.

Around June 18, 2026, however, IRCC added detailed information that’s especially relevant for Canadian ancestors born in the 1800s.

The most useful change is this: there’s no stated requirement to search for a birth registration or baptism record before using census records to prove an ancestor was born in Canada.

The revised page is available here, but I’ve included relevant screenshots below, because it’s clear this page is liable to change.

A newly added list called “What we accept” says, “[Y]ou must provide . . . 1 of the following documents,” and then, of all the documents listed, only one would be relevant for a Canadian-born ancestor, namely, a “provincial or territorial birth certificate.” (See screenshot, below.)

What if there’s no birth certificate?

If you’re applying for a certificate under the provisions enacted by Bill C-3, your Canadian ancestor was probably born before the earliest birth year for which their province’s vital statistics agency issues birth certificates. In that case, a birth certificate is not available.

That’s because, after a legislated period of time, the birth registrations that each province’s vital statistics agency uses to create birth certificates are transferred to the provincial archives. For those years, the vital statistics agency can no longer issue a birth certificate.

The following chart shows the earliest birth years for which each province can issue a birth certificate:

Province	Earliest year available (birth registration retention period)
British Columbia	1906 (120 years)
Alberta	1906 (120 years)
Saskatchewan	1926 (100 years)
Manitoba	1926 (100 years)
Ontario	1922 (104 years)
Quebec	1994 (birth certificates can be issued retroactively by the Directeur de l’état civil)
New Brunswick	1931 (95 years)
Nova Scotia	1926 (100 years)
Prince Edward Island	1906 (120 years)
Newfoundland and Labrador	1926 (100 years)

If a birth certificate is not available, what document(s) will prove my ancestor was born in Canada?

IRCC’s new instructions are clear. (Well, sort of clear.) The documents you provide should probably be certified copies. And a new section called “If you’re missing any birth certificates” provides a helpful list of acceptable documents that includes records of birth, baptismal records and census records.

Certified copies are required. (Sort of.)

The new requirements don’t explicitly state you must provide certified copies. However, the documents must be issued by the “original authority” that keeps the originals (e.g., the archives), and must “clearly show who issued the document.”

So while IRCC doesn’t use the term “certified copy,” they’ve exactly described a certified copy of a birth registration, baptism or census record: the original is kept by an archives and the copy includes the name of the official who issues it.

Again, given the likelihood of web-page change, I will use a screenshot to document this instruction:

Birth registrations, baptism and census records: all the same to IRCC?

The new instructions include a section called “If you’re missing any birth certificates.” This will absolutely be the case for an ancestor born in Canada before the earliest year in the table above for their province.

In this case, IRCC will accept any of the following, as long as it was “issued by the original authority that created or keeps the record” and clearly shows who issued it:

• a record from a physician or midwife who witnessed the birth
  • (Much like IRCC’s description of what are essentially certified copies (see above), this is probably “IRCC-speak” for a birth registration)
• baptismal certificate or record
• census records

Again, because these instructions may change again, here is a screenshot:

Do I have to prove I tried to get a birth registration and/or baptism before I can use census records as proof?

No. According to IRCC’s new instructions, there is no requirement to prove you tried to get a birth registration or baptism record before using census records. (You do still have to show you tried to get a provincial or territorial birth certificate, as explained below.)

The new requirements are presented in three sections:

“Documents proving Canadian citizenship of your parent, grandparent and parental ancestor”

This is the section that states the requirement for documents that are issued or kept by an “original authority” and clearly show who issued them. Here is a screenshot:

“What we accept”

This is the section that indicates you must provide a provincial or territorial birth certificate to prove the citizenship of a Canadian-born ancestor. (See the first screenshot in this post.)

“If you can’t provide official documents issued by the original authority”

In this section, IRCC’s use of the term “official documents issued by the original authority” may be confusing — until you look at the list of documents in the previous section, which includes:

• birth certificates
• citizenship and naturalization certificates
• Certificates of Registration of Birth Abroad
• Certificates of Retention of Canadian Citizenship
• British naturalization certificates issued in Canada or Newfoundland and Labrador

These are all “official documents” that were “issued” to individuals by government authorities.

On the other hand, the documents listed in the sub-section called “If you’re missing any birth certificates” were either never issued to anyone or never counted as “official documents.”

Therefore, these instructions apply when you can’t provide — specifically — a provincial or territorial birth certificate for an ancestor born in Canada. As we’ve seen, a provincial or territorial birth certificate is the only “official document issued by the original authority” in the list provided (see “What we accept”) that applies to someone born in Canada.

So if you can’t provide a provincial or territorial birth certificate — which is the case for everyone born in Canada before the earliest year their province issues birth certificates — you can move on to other types of documents. (See the third screenshot in this post.)

With these new instructions, once you work through the language, IRCC made their documentation requirements for anyone born in Canada very clear. Regardless of when the birth occurred, IRCC wants to see a provincial or territorial birth certificate.

This preference for a Canadian birth certificate is probably why IRCC doesn’t rank the alternatives they’ll accept “If you’re missing any birth certificates.” If you can’t provide a birth certificate — i.e., the only “official document issued by the original authority” they name that applies to a Canadian-born individual — an archival birth registration is no better for their decision making than a baptism record, and neither is better than census records. IRCC’s unranked list of these alternatives, and the lack of any other instructions for their use, make it reasonable to infer they are of equal evidentiary weight.

Census records: the low-hanging fruit of 19th-century citizenship proof

Canadian census records are available online for each decade from 1851 to 1931. Copies printed from Library and Archives Canada’s “Census search” database can be used to support a citizenship certificate application. There’s no need to order certified copies. This is made clear by a notice that appears at the bottom of each results page:

According to IRCC’s new instructions, to prove a Canadian-born ancestor’s citizenship using census records you must do two things:

1. Explain in writing why you can’t provide a birth certificate, which would be the “official document issued by the original authority” that proves their citizenship. (Their birth predates the earliest birth certificates issued by their province’s vital statistics agency.)
2. Show proof that you tried to get a birth certificate from the relevant vital statistics agency (e.g., an email exchange with the province’s vital statistics agency requesting a birth certificate for someone born in [insert year here, e.g., 1868], and their reply).

Putting it together

In other words, if census records show your ancestor was born in Canada, IRCC’s new instructions let you submit them without first searching for a birth registration or baptism. You will still need to explain why no birth certificate is available, and show you tried to get one.

A final lesson from IRCC’s June 2026 update: screenshot the instructions as they appear on the day you apply, and consider including them with your application. As of this writing, citizenship certificate applications take about three years to process. The page you relied on may not be the page your application is judged against, so keep proof of what it said.

This was an AI-aided project that used a series of tax, church and land records to establish the presence of John Wall and his family in Canada between 1848 and 1864.

The records clearly establish his family’s presence in Ontario in this period.

But the value of the AI tool (in this case, Claude) was the rapid development of an interactive timeline and the logical classification of facts (Documented), theories (Plausible) and areas for additional research (Unknown).

Canada’s citizenship law changed on December 15, 2025. Effective that day, thousands — possibly millions — of people born outside Canada who have a Canadian ancestor became Canadian citizens.

Since then, many have come to us with questions about Canadian citizenship by descent. That makes sense, because we’re a Canadian genealogical research company. We help clients find information about their ancestors, and we use genealogical research methods and archival sources to prove family connections.

But if you’re considering our services because you’re applying for a certificate of Canadian citizenship, here are some important points.

Certified birth certificates

One thing is clear from the information provided online by Immigration, Citizenship and Refugees Canada (IRCC). They want to see “Birth certificate[s] showing parentage, issued by the responsible government authorities in the country where the person was born.” (See Documents establishing citizenship.)

Obtaining certified copies of birth records from government agencies is something you’ll need to do yourself, because the agencies might require a copy of your I.D., and they might need to know your relationship to the person named in the record.

Older birth records / no birth records

On the other hand, IRCC does not provide information about what documentation they require in historical cases such as:

• an ancestor born before their birth province started registering births (e.g., Ontario before 1869);
• an ancestor born during a time of official birth registration, but no registration exists (e.g., a significant percentage of Ontario births after 1869 were never registered);
• an ancestor whose provincial birth registration, due to its age, has been transferred from the government authority that issues birth certificates (e.g., ServiceOntario) to the provincial archives (e.g., the Archives of Ontario) who make images of birth records available online (e.g., through a partnership with Ancestry.com).

For cases like these, genealogists typically use the image copies of records on Ancestry.com and other family-history websites. We do this because, “in historical research, … [an image copy] is typically treated as an original, so long as no evidence suggests that the image may have been altered.” (Elizabeth Shown Mills, Evidence Explained, 3 rev. ed. (Baltimore, MD: Genealogical Publishing, 2017), 825.

This is an image copy of John McDonald’s 1855 Ontario baptism with a complete source citation:

This image would be an acceptable representation of the original document in a genealogical report. However, IRCC signalled in a recent stakeholder meeting (May, 2026) that they will not accept documents sourced from Ancestry.com — or, presumably, other any online resource. This guidance does not appear in IRCC’s public-facing information.

So when a genealogist provides you with images of archival documents from Ancestry.com or other online resources — standard practice in genealogy — you may need to obtain copies of the same records directly from the archives if you’re using them to apply for a certificate of Canadian citizenship.

According to IRCC, an applicant should be able to complete the process without assistance:

You can get all the forms and instructions you need to apply for a visa, a permit or citizenship for free on this website. If you follow the instructions, you should be able to fill out the forms and submit them yourself.

But given the conflict between genealogical practice and IRCC requirements, we recommend consulting a citizenship representative who specialises in Canadian citizenship by descent, because they may have received guidance directly from IRCC.

What a genealogist can do

Genealogists are experts at using archival records to prove questions of identity and kinship.

For example, when no birth record exists, we use the Genealogical Proof Standard (GPS) to prove the case. The GPS requires us to undertake reasonably exhaustive research, create complete source citations, test and analyse the evidence, resolve any conflicting information and provide the results in a coherently written format. (Board for Certification of Genealogist, Genealogical Standards, 2nd. rev. ed. (Nashville, TN: Ancestry, 2021).)

Consider this case: If your ancestor, John McDonald, was born in Clarence Creek, Ontario in 1855, he won’t have a birth certificate because Ontario didn’t start registering births until 1869. That doesn’t change the fact that the ancestor was born in Canada.

In a case like this, a genealogist can find and assess a variety of historical documentation to prove John McDonald was born in Canada. In addition to his 1855 Ontario baptism record, he may be listed with his parents in the 1861 census of Canada West. Those two documents, included in a written report, would provide genealogical proof that John was born in Canada.

This approach is consistent with IRCC’s guidance about Applications for citizenship certificates, which says:

The documents required to establish citizenship vary depending on the requirements of the provision of the Citizenship Act under which citizenship is being established.

All applicants must provide

• documents establishing citizenship outlined in the document checklist at the end of the Application for a Citizenship Certificate for Adults and Minors (Proof of Citizenship) Under Section 3 form;
• other documents, as required, for the assessment of the claim to Canadian citizenship and the possible loss of citizenship.

So if your ancestor was born in Canada before provincial birth registration, you may still be able to establish your Canadian citizenship. IRCC’s language is broad enough to allow for additional documentation (i.e., “other documents … for the assessment of the claim”), though it gives no specific guidance on documentation for ancestors with no official birth record.

Here’s what we can do

We can research your family history, identify the records that exist, locate the provincial or territorial agencies that hold them, and — where no birth or baptismal record survives — prepare a Canadian ancestry or birth evidence report that meets the Genealogical Proof Standard.

Here’s what we can’t do

We can’t tell you what documents IRCC will require or accept for your application.

We can’t obtain certified copies of birth records from provincial or state agencies.

Under the Citizenship Act, we can’t advise you — directly or indirectly, and for payment — in connection with your citizenship application. That role belongs to a lawyer, Quebec notary or licensed immigration consultant.

Our promise to you

What we can promise is that when you come to us, you’ll know exactly what the historical record says about your ancestor’s Canadian birth and your Canadian lineage. That’s the foundation any citizenship application needs — and it’s what we do best at dfh Research Services.

If you can prove your descent from an ancestor born in what is now Canada … the answer might be “Yes”!

Canada’s first Citizenship Act came into effect on January 1, 1947. Anyone born in Canada before that date was considered a “natural-born Canadian” as long as they had not lost their status as a British subject prior to that date:

4. A person, born before the commencement of this Act, is a natural-born Canadian citizen:–
   (a) if he was born in Canada … and has not become an alien at the commencement of this Act.

Posthumous application?

This applied to anyone born in Canada before January 1, 1947. But did it also apply to those who were born in what is now Canada, but who had died before that date?

Section 3(1.5) of the current Citizenship Act provides for the transmission of citizenship from some deceased citizens to children born outside Canada. But only those whose parent or grandparent has died:

(1.5) A person who would not become a citizen under one of the paragraphs of subsection (1) for the sole reason that their parent or both their parent and their parent’s parent died before the coming into force of An Act to amend the Citizenship Act (2025) is a citizen under that paragraph if that parent — or both that parent and that parent’s parent — but for their death, would have been a citizen as a result of the coming into force of that Act.

Despite this paragraph in the current Act, if the 1947 Act applied to those who were born in what is now Canada, but who had died before January 1, 1947, it included Acadians born on the peninsula of what is now Nova Scotia; they became British subjects after the Treaty of Utrecht in 1713. It also included anyone born in the northern part of New France (then called Canada), and the island of Newfoundland, which came under British rule after the Treaty of Paris in 1763.

All those people were born in what is now Canada “before the commencement of this Act.” As long as they did not lose their status as British subjects, did each become a “natural-born Canadian citizen” on January 1, 1947?

More importantly, if everyone born in what is now Canada before January 1, 1947 became citizens under Section 4(a) of the first Citizenship Act, their children born outside Canada up to January 1, 1947 also became Canadian citizens under Section 4(b) (and subsequent amendments that removed discriminatory circumstances):

A person, born before the commencement of this Act, is a natural-born Canadian citizen:–
(b) if he was born outside of Canada … and his father [read: parent] … was born in Canada

This Act created a first-generation limit on the transmission of Canadian citizenship for those born outside Canada.

First Generation Limit

This first generation limit was partly amended by the 1977 Citizenship Act. Under that Act, a child born outside Canada to a Canadian parent was Canadian. But only if the child was born after February 15, 1977:

3. (1) Subject to this Act, a person is a citizen if
(b) he was born outside Canada after the coming into force of this Act and at the time of his birth one of his parents … was a citizen

Thirty years later, in 2009, Bill C-37 amended the Citizenship Act by adding Sections 3(3), paragraphs (a) and 3(b) to prevent the children of Canadian citizens who were themselves born outside Canada from becoming citizens at birth — thus enshrining a First Generation Limit.

Bill C-3 An Act to amend the Citizenship Act

In 2023, Justice Akbarali found the First Generation Limit in the Citizenship Act to be unconstitutional, and therefore of “no force and effect.”

In response, the Parliament of Canada passed Bill C-3 An Act to amend the Citizenship Act (2025), which came into effect on December 15, 2025. This amendment removed the First Generation Limit of Section 3(3) and replaced it with a parental residency requirement — but only for those born outside Canada on or after December 15, 2025.

Implications

It would seem, then, that with no generational limit on the transmission of citizenship to those born outside Canada, Canadian citizenship has been passed down, in some cases, for more than 300 years from distant ancestors who became “natural-born Canadian citizens” by virtue of the 1947 Act to all descendants born outside what is now Canada.

This interpretation seems confirmed by publicly available reports of applicants receiving their certificates of Canadian citizenship based on “Gen 0” ancestors born in Acadia in 1730 and Quebec in 1806.

Present-day descendants

Today, Canadian citizenship by descent presumably applies to anyone 49 years or older (i.e., born before February 15, 1977) who was born outside Canada to a Canadian parent, as stated in Section 3(1)(d) of the Citizenship Act:

Subject to this Act, a person is a citizen if
(d) the person was a citizen immediately before February 15, 1977.

By extension, children of those who were citizens before February 15, 1977, and who were born outside Canada, would be citizens under Section 3(1)(b) of the Citizenship Act:

Subject to this Act, a person is a citizen if
(b) the person was born outside Canada after February 14, 1977 and at the time of his birth one of his parents, other than a parent who adopted him, was a citizen.

The only limit might be the dates on which various parts of Canada came under British rule.

The next step — for anyone wanting to confirm their Canadian citizenship — is to apply to Immigration, Refugees and Citizenship Canada for a certificate of Canadian citizenship. (There’s also a process for those who want to renounce their “new” citizenship.)

DNA Identifies the Father of an English-born Child

Growing up in London, England, Elaine’s biological father was a mystery. Her mother said he had been a Canadian airman stationed in Europe in the late 1950s. Beyond that, there were no names, no records, no photographs — just a story, repeated but never explained.

For decades, Elaine wondered who her father was. In time, genetic genealogy would lead to the answer.

---

Following the DNA Clues

When Elaine first looked through her DNA results, she noticed something interesting and quite surprising: many of her closest paternal matches were from Western Canada, particularly from families with roots in German immigrant farming communities that had settled in southern Manitoba and Saskatchewan.

Two names began appearing again and again among her matches’ family trees:
Schmidt and Dawson.

One group of matches traced back to a Schmidt family who had lived on the Canadian Prairies for generations. Another cluster of matches traced back to a Dawson family in the same area.

These findings prompted further research to identify a “union couple” — perhaps a marriage between a member of the Schmidt and Dawson families — because descendants of that couple would have inherited the same DNA pattern found in Elaine’s results. In other words . . .

Elaine’s father was probably the son of a Schmidt parent on one side, and a Dawson parent on the other.

Additional evidence indicated the Schmidt parent was likely Elaine’s grandfather. Further research showed there was only one son born to a Schmidt father and a Dawson mother in the right time period, and in the right place. That son would later serve in the Canadian military in the 1950s.

---

A Brief Marriage, a Young Son, a Difficult Loss

In the early years of the 20th century, Ernst Schmidt — a young farmer — married Lillian Dawson, the daughter of a nearby homesteading family.

Their marriage was heartbreakingly short. Lillian died just two years later, likely due to complications following childbirth. She left behind two small children — a baby boy named Peter and an infant daughter.

Peter grew up in rural Manitoba and enlisted in the Canadian military as a young man.

Publicly available military records showed his unit was posted to Germany in 1957. But whether he was ever in London around that time remained a mystery.

---

DNA Confirmation Strengthened the Case

To test the theory that Peter Schmidt was Elaine’s biological father, dfh DNA Family Help compared the amount of DNA Elaine shared with matches on both sides of Peter’s family — Schmidt relatives and Dawson relatives.

The numbers aligned perfectly with what would be expected if Peter Schmidt were Elaine’s biological father.

Every piece of evidence — DNA clusters, shared matches, family connections, timelines, and geographic movement — pointed to the same conclusion:

Elaine’s father was almost certainly Peter Schmidt, a Canadian soldier born in Manitoba in the 1930s.

Peter passed away in the late 1990s, but traces of his life remain — including a gravestone in Western Canada that includes the insignia of his military regiment, and his military personnel file, which remained in the archives of the Department of Defense. After the genetic investigation concluded, Peter’s niece obtained a copy of that file, which proved Peter was in London the year before Elaine’s birth.

---

A Life Reconnected

For Elaine, the discovery was deeply meaningful. Her ancestry wasn’t the story of a brief romance during the Cold War that faded into silence.

It was the story of Canadian prairie farms, immigrant grit, young love, loss, and a branch of family never knew she existed — until DNA helped bring the pieces back together.

---

Canadian Citizenship by Descent

Elaine’s discovery made her eligible to apply for a certificate of Canadian citizenship. That’s because “In 2009, you became a Canadian citizen if you: were born outside Canada in the first generation to a Canadian parent on or after January 1, 1947, and you lost or never had citizenship due to former citizenship provisions.” (Source: https://www.canada.ca/en/immigration-refugees-citizenship/services/canadian-citizenship/act-changes/rules-2009-2015.html)

Recent changes to the Citizenship Act removed that first generation limit.

Because her father was in the Canadian Armed Forces at the time of her birth, Elaine could also pass her citizenship to her UK-born children. That restriction (that a person in the second generation born outside Canada was a Canadian citizen only if their grandparent was in the Canadian Armed Forces, or the federal public administration, or the public service of a province or territory at the time of their parent’s birth) changed on December 15, 2025, when Bill C-3 amended the Citizenship Act to remove the “First Generation Limit.” Now, according to an email received from the office of the Minister of Immigration, Refugees and Citizenship Canada, the law is simply this:

To be eligible for Canadian citizenship by descent, a person born abroad before December 15, 2025 must have an ancestor who became a Canadian citizen on or after January 1, 1947 (or on or after April 1, 1949, in Newfoundland). This includes those whose ancestor became a citizen through the 2009, 2015, or 2025 amendments to the Citizenship Act.

In Elaine’s case, she not only identified her biological father, she and her children also became Canadian citizens. All thanks to the power of DNA!

All names in this post have been altered for privacy.

When Marjorie set out to learn more about her family history, she thought she already knew who her grandfather was. Her mother’s birth certificate, baptism record, and even the 1931 Canadian census all pointed to the same man: Harold Benson, an electrician living in Montreal. Although Harold was not married to Marjorie’s maternal grandmother, he was consistently listed as the father of her child.

But something about the story didn’t quite add up.

For one, Harold was listed as being born in England, the son of English parents. Yet Marjorie’s DNA results showed a strong connection to Finland—about 30% of her ancestry. That was far too much to ignore. Could it be that her family’s story had been misunderstood—or perhaps deliberately altered—nearly a century ago?

---

The Trail Begins in Montreal, 1931

The census of 1931 shows Harold Benson living with Marjorie’s grandmother, Clara Whitfield, and their infant daughter, Irene (Marjorie’s mother). He was an electrician in the paper mill industry. Family stories suggested he died in a tragic mining accident not long after Irene was born, but searches of accident records turned up nothing.

Meanwhile, just a few blocks away, another man appeared in the same census: a Finnish immigrant named Harold Simonson who was also an electrician. He lived in a small apartment with a roommate—Carl Niemi, a fellow Finn.

Two men, both electricians, both named Harold, both enumerated a few blocks from each other in Montreal. Coincidence? Or was there a deeper connection?

Following the DNA

Marjorie’s closest DNA matches on her mother’s side connected her not to England, but to extended Finnish families. As the research progressed, the surname Lauhakangas consistently appeared. It linked a large cluster of Marjorie’s matches to a set of common ancestors in rural Finland in the 1800s.

The strongest theory that emerged was this: Marjorie’s true grandfather was not Harold Benson (aka Harry Simonson)—but his roommate, Carl (“Charlie”) Niemi, the Finnish electrician who shared a flat with Harry Simonson.

Carl had come to Canada from Finland in the 1920s. Records show that in 1941, a decade after Irene’s birth, he married a Finnish woman named Elsa Korhonen in Montreal. His mother’s name was listed as Tekla Lauhakangas—the same surname that appeared over and over again in Marjorie’s DNA connections.

A Finnish Legacy

If this theory were correct, then Harry Simonson’s roommate, Carl Niemi, was likely Marjorie’s biological grandfather, and her family story stretches back to Finland, not England. The DNA matches fit the puzzle: Marjorie’s connection to a distant cousin, Katherine Olson, was exactly the right amount for them to share great-great-grandparents through the Lauhakangas line.

Suddenly, the pieces make sense. The unexplained Finnish DNA. The mysterious “Harold Benson” who seemed to vanish from later records. The neighbouring Finn named Harold Simonson who may have been mistakenly—or perhaps intentionally—recorded as Irene’s birth father. And Harold’s roommate, Carl Niemi, whose genetic heritage linked him to Marjorie through her Montreal-born mother.

The Road Ahead

Like many family mysteries, this one will need a bit more work. More research into Finnish records, and DNA testing of Carl Niemi’s descendants, will likely provide the best possible evidence that Carl was Irene’s father. But for Marjorie, the story has already shifted:

Her mother’s real story wasn’t about an Englishman lost in a mining accident—it was about a Finnish immigrant who came to Montreal seeking opportunity, and whose story became entwined with hers.

And thanks to DNA, an untold history has finally been revealed.

? Stories like Marjorie’s show how DNA can uncover forgotten chapters of family history. Sometimes the truth is hiding just a few blocks away—or across the ocean.

In April 1665, Richard Sainsbury, a carpenter of London, made his last will and testament.¹ In it, he bequeathed several leasehold properties in Southwark, Surrey, to his wife Rebecca for the duration of her life. He specified that upon her death, the lease of his residence and an adjoining tenement on the east side were to pass to his granddaughter, Rebecca Leeson. However, this gift came with a condition: Rebecca Leeson was to release her brother, John Leeson, from a legacy bequeathed to her by their father, Henry Leeson, totaling more than £30.

Richard Sainsbury died shortly after making his will, which did not name an executor. His wife, therefore, obtained letters of administration for his personal estate, giving her control over his assets. She then surrendered the leases originally held in Richard’s name to their ground landlord, Edward Potkin, and secured new leases in her own name, maintaining the same terms. Although she was only allowed to use the properties during her lifetime, in 1667 she rented part of the property to a man named Richard Jeffes for sixteen years—which was the amount of time left in the lease that Richard Sainsbury had originally signed.

In about 1675 (although no record has been found), Rebecca Sainsbury’s granddaughter Rebecca Leeson married John Tomlinson, a feltmaker from Southwark. About three years later, in 1678, her grandmother, Rebecca Sainsbury, died. Before her death, she made a will and appointed her son-in-law John Spicer as executor.² Spicer took control of her possessions, including the leases. (Incidentally, Rebecca Sainsbury’s will included a bequest to her niece, Elizabeth Griffin, “now inhabiting in Virginia.” Mentioned here because wills of this period rarely name English emigrants to the American colonies.)

Initially, Spicer allowed his step-daughter Rebecca and his son-in-law John Tomlinson to take possession of and collect rents from the property that was bequeathed to Rebecca (Leeson) Tomlinson by her grandfather Sainsbury—and which her grandmother Sainsbury had then leased to Richard Jeffes. But after Rebecca’s untimely death in early 1681, Spicer became hostile. He was likely angry, in part, because he “had mainteined the said Rebecca the comp[lainan]ts wife whilest she was seke for many yeares. . . .”³ Spicer threatened to dispossess Tomlinson of the property in question and sued Richard Jeffes, Tomlinson’s tenant, for unpaid rent and breach of lease covenants. John Tomlinson responded by filing a complaint in the Court of Chancery in June 1681, asserting his late wife’s entitlement to the lease under her grandfather’s will, and accusing his late wife’s step-father John Spicer and his brother-in-law John Leeson of unjust behaviour. (Ref. C 8/304/47; digital images acquired by author.)

Spicer and Leeson responded in July 1681, acknowledging the will of Richard Sainsbury and the lease to Richard Jeffes but insisting that Rebecca (Leeson) Tomlinson had failed to meet the condition attached to her inheritance: she had not released her claim to the full legacy from her father. In fact, Tomlinson and his wife had sued John Leeson in the Court of Exchequer in 1678–soon after Rebecca Sainsbury’s death—for the full sum of £200. Eventually, they reached a settlement for £60, which Spicer and Leeson claimed nullified her right to the leasehold estate.

Additionally, John Leeson admitted to having some of the late Rebecca (Leeson) Tomlinson’s belongings, including a silver tankard and linens, valued at £7 9s. However, he asserted a legal right to them, having had them condemned in the Sheriff’s Court of London to satisfy a debt Tomlinson owed him.

Thus, by mid-1681, the matter stood unresolved: Tomlinson claimed the leasehold estate by right of his late wife, while Spicer and Leeson contested this on the grounds that she had forfeited her inheritance by claiming her full legacy from her father. Meanwhile the tenant, Richard Jeffes, faced possible eviction, financial loss, and legal confusion, all because of a tangled inheritance dispute and uncertainty over who actually had the right to lease the property in a conflict that spanned three generations.

For many descendants, Daniel Sansbury (c.1740s/50s?-1816) of Darlington County, South Carolina, has been a “brick wall” ancestor. Identifying his paternal line and his immigrant ancestor has been a long-standing challenge. But recent research combining Y-DNA analysis and archival records may shed new light on Daniel Sansbury’s origins.

Full Report

The Sainsbury-Sansbury group project on FamilyTreeDNA was established, in part, to tackle this very problem. Through this project, a unique genetic pattern emerged in a set of Y-DNA test takers that connects Daniel Sansbury’s descendants to several Sainsbury families whose paternal lines trace back to Wiltshire, England.

This specific genetic pattern, currently defined as Y-DNA haplogroup R-FTA27580, strongly indicates that Daniel Sansbury’s ancestors were most likely Sainsburys who lived in Wiltshire as far back as the 1500s.

AI-Generated Podcast (Report Summary)

Drawing on this genetic evidence and using historical records, the report proposes a patriline that links Daniel Sansbury to George Sainsbury of Trowbridge (c.1535-aft.1586).

Crucially, the report identifies a possible immigrant ancestor: a boy or young man named Daniel who left England in late 1678 for the Colony of Virginia. After his arrival, he worked for more than eight years as an indentured servant.

Court records from Old Rappahannock County, Virginia document his efforts to gain freedom after his eight-year term of service ended in January 1686/87. Eventually, in May, 1689, he was ordered “free from any further time of service” and by November 1699, he was married to a woman named Phebe.

If this couple had children in the late 1600s, one may have been the ancestor of Daniel Sansbury of Darlington County a generation or two later. This hypothesis, based on evidence presented in the report, marks a significant step forward in identifying—or at least hypothesizing—a paternal lineage for Daniel Sansbury of Darlington County.

What does a genetic genealogist do? Well, after you’ve submitted your DNA to multiple databases and shared those results with me, here’s what I do — depending on your unique situation — to achieve or advance your research goal.

As you’ll see, this is a time-intensive process that requires patience and persistence! It also requires adequate DNA matches and the availability of written records.

1. I Organize Your DNA Matches
   I group your matches using methods such as the Leeds Method. This creates clusters of cousins who are related to you — and each other — through at least one common ancestor.
2. Distinguish Maternal and Paternal Lines
   I separate matches into maternal and paternal branches to focus on the relevant lineage that contains your unknown ancestor.

The first two steps can typically take about a day. They may be completed during a six-hour research contract. You may then decide to complete the next steps yourself, or hire me for part of the work, or arrange a face-to-face session where I can teach you how to accomplish the next steps yourself.

3. Consider DNA Amounts and Build Family Trees for Close Matches
   At this point, I concentrate on your closest matches in the relevant group. I use the Shared cM Project to consider how much DNA they share with you and how they might be related to you. I also identify the most recent common ancestor(s) (MRCAs) that link many or all your matches in the relevant clusters. Then I may expand the tree sideways to include siblings of the MRCAs and work downward — if records are available — to the present generation. The goal here is to identify individuals who fit the time and location for the conception event.
4. Consolidate Family Trees
   With more research, especially into marriage records, and considering geography and ethnicity, I try to link separate family trees by identifying couples whose children would have inherited DNA from at least two previously identified clusters.

Building family trees takes time. Several trees are typically built at the same time and they require a lot of records searching to ensure accuracy. Tens of hours are typically spent on these steps.

5. Analyze Clusters and Use the WATO Tool
   After identifying a cluster of descendants from the suspected MRCA, I may use the “What Are The Odds plus” (WATO plus) tool to formulate and test hypotheses about potential parents.

This phase requires good data input and expert analysis to work through the options and consider which hypotheses are most likely.

6. Present a Hypothesis
   If enough DNA matches are present, and the records exist to support a theory, I’ll present a hypothesis of the unknown ancestor’s identity. This will likely need to be tested with more evidence, for example: targeted DNA testing among the proposed ancestor’s nearer relatives and any information those family members may have about the proposed connection to your family.

At the end of each research session I write a formal report. This is your record of what was found in the process, and what all the information means for your research goal.
