Acadian genealogy is a parallel system to Quebec genealogy. The two French-speaking populations of early Canada — Quebec on the St. Lawrence, Acadia in the Maritimes — were separated by geography, by their relationship to the British Crown after 1713, and by the catastrophic 1755 Deportation that scattered Acadian families from Nova Scotia to Louisiana and back again. Researching Acadian and Maritime Canadian lineage requires different archives and a different methodology.

If your ancestors lived in present-day Nova Scotia, New Brunswick, Prince Edward Island, or Newfoundland and Labrador, this is your guide. For the Quebec equivalent, see Quebec genealogy resources — PRDH, Drouin, BMS2000, Tanguay.

Two distinct populations, often confused

Acadians and Quebecois are both French-Canadian, but they're not the same population. The distinctions matter because they lead to different archives.

  • Acadians settled in present-day Nova Scotia from the 1630s, with later expansion into New Brunswick and PEI. They were French but governed by the British after 1713 (Treaty of Utrecht). Distinct French dialect. Distinct family-name pool: Arsenault, Cormier, Boudreau, Doiron, LeBlanc, Maillet, Mazerolle, Melanson, Robichaud, Thibodeau, Vautour.
  • Quebecois settled the St. Lawrence valley from 1608 onward, governed by France until 1763, then by Britain. Modern Quebec French. Different surname pool, though overlap exists.
  • Cape Breton Highland Scots arrived in Nova Scotia from the late 1700s, fleeing the Highland Clearances. Largely Presbyterian and Catholic. Surnames: MacDonald, MacLeod, MacKenzie, MacIntyre, Gillis.
  • Loyalists came north from the American colonies after 1783. Mostly English-speaking Protestants. Concentrated in Saint John and the western New Brunswick valley.
  • Irish Famine migrants arrived in the Maritimes from the 1840s, with Saint John and Halifax as primary entry points. Both Catholic and Protestant.

The first task in Maritime genealogy research is identifying which population your ancestor belonged to. The surname plus the parish or region usually gives this away.

The 1755 Deportation and its documentary consequences

In 1755 the British colonial government forcibly removed roughly 12,000 Acadians from Nova Scotia. They were dispersed to the American colonies (where many were turned away), to England (where some were held as prisoners), to France (where they were ill-fitting after generations away), and to Louisiana (where they became the ancestors of present-day Cajuns).

The Deportation destroyed the Acadian record base in three ways:

  1. Many parish registers from the 1710s–1750s were burned or lost in the chaos.
  2. Families were broken up; siblings ended up in different countries.
  3. The Acadians who returned after 1764 (when the British allowed it) often returned to different villages than they'd come from, creating discontinuities in the documentary record.

What survives is partial but workable. Stephen White's Dictionnaire généalogique des familles acadiennes, published in 1999, reconstructs Acadian genealogy from 1636 to 1755 using every surviving record fragment. It's the Tanguay-equivalent for Acadian research and the starting point for anyone tracing an Acadian line.

Where to look, by province

Nova Scotia

The Nova Scotia Archives holds:

  • Civil registration of births, marriages, and deaths from 1864 onward
  • Earlier Catholic parish registers (Acadian, 1714–1860s) on microfilm
  • Anglican parish registers from 1749 (founding of Halifax) onward
  • Presbyterian and Baptist parish registers from various 18th–19th century starts

For certified copies of post-1864 civil records, request through Vital Statistics Nova Scotia. Fees: $35 CAD for a long-form certificate, 6–8 weeks turnaround.

For pre-1864 parish records, the Public Archives of Nova Scotia and the Centre acadien at Université Sainte-Anne are the primary repositories. Many Acadian records were microfilmed by the LDS Church and are searchable on FamilySearch.

New Brunswick

The Provincial Archives of New Brunswick holds:

  • Civil registration from 1888 onward
  • Earlier parish registers (Catholic Acadian, Catholic Irish, Anglican, Methodist, Presbyterian) on microfilm and increasingly digitised
  • The largest single archive of Acadian post-Deportation records

For Acadian researchers specifically, the Centre d'études acadiennes Anselme-Chiasson at the Université de Moncton holds the largest single collection of Acadian genealogical material. Their reading room is open to researchers; remote-research queries are accepted for a fee.

Vital statistics certificates: Service New Brunswick charges $30 CAD for a long-form certificate, 4–6 weeks turnaround.

Prince Edward Island

PEI is smaller — population about 170,000 — and its archives are correspondingly smaller but better-curated.

The Prince Edward Island Public Archives and Records Office holds civil registration from 1906 (later than other provinces because PEI didn't centralise earlier). For pre-1906 ancestry, Catholic parish registers held by the Diocese of Charlottetown (founded 1829) are the primary source.

PEI's role in Acadian history was significant: many Acadians fled to PEI (then Île Saint-Jean) before the 1755 Deportation, and PEI was the launching point for some of the post-1764 returns to the Maritimes. The La Société d'histoire de la mer rouge maintains the most thorough Acadian-PEI database.

The recent IRCC.com news item Prince Edward Island Archives logs four years worth of document requests in four months describes the post-December 2025 surge — PEI Archives received as many requests in early 2026 as in the four preceding years combined. Plan for delays.

Newfoundland and Labrador

Newfoundland's situation is distinctive. The colony didn't join Canada until 1949. People born in Newfoundland before that date were British subjects, not Canadian citizens — but the 1949 union retroactively conferred Canadian citizenship on most of them.

For descent claims involving Newfoundland ancestry, the December 2025 reform applies, but the documentary chain has an extra step. The Newfoundland-born ancestor needs to be documented as resident in Newfoundland on March 31, 1949, the date of union. After that date, normal Canadian descent rules apply.

The Maritime History Archive at Memorial University holds the largest collection of Newfoundland genealogical material. The Provincial Archives of Newfoundland and Labrador holds civil registration from 1892.

Louisiana Cajun lineages: a special case

If your ancestry runs through Louisiana, and family memory mentions Acadian roots, you may have a documentable claim through the deported Acadian population.

The path: Louisiana Cajun → Acadian deportation refugee → Nova Scotia (or New Brunswick) Acadian ancestor → eligibility under the 2025 reform.

Resources:

The chain from a present-day Louisianan back through Cajun-Acadian-Nova Scotian lines is documentable but slower than direct Acadian-Maritime work. Plan for 3-6 months of research vs 1-3 months for a straight Maritime line.

Common Maritime research problems

Surname variants

Acadian surnames went through significant spelling changes during and after the Deportation. The same family might appear as:

  • LeBlanc in Acadia 1750
  • White in New England 1760 (translated by English-speaking clerks)
  • Leblanc in Louisiana 1810 (recapitalised)
  • LeBlanc in modern Acadia (back to original)

Search every variant. The Stephen White Dictionnaire cross-references variants.

Pre-1864 records in Nova Scotia

The lack of civil registration before 1864 means Acadian and other pre-Confederation ancestors are documented only through parish registers. For Acadian families, this is usually the Catholic parish; for Loyalist families, the Anglican church; for Cape Breton Scots, the Presbyterian session register.

Some parishes — especially smaller rural ones — have registers that were destroyed by fire or water damage. The Public Archives of Nova Scotia holds an index of which parishes have surviving records.

Catholic vs Civil parallel registers

After Nova Scotia and New Brunswick introduced civil registration (1864 and 1888 respectively), families often registered births in both the parish and with the province. Some registered in only one. For descent applications, IRCC accepts either, but having both strengthens the case.

What IRCC accepts from Maritime archives

Same general rules as Quebec:

  • Certified extracts from the Nova Scotia Archives, Provincial Archives of New Brunswick, PEI PARO, or the relevant diocesan archive — gold standard.
  • Vital Statistics certified copies for post-civil-registration births, marriages, deaths.
  • FamilySearch images of microfilmed parish registers — accepted, with source citation.
  • Stephen White Dictionnaire entries — accepted as supporting evidence; pair with parish source where possible.

The general application checklist is in Documents required for proof of Canadian citizenship application — full checklist.

A common Maritime applicant profile

Many American applicants discovering Maritime ancestry didn't know they had it. The "I thought I was French-Canadian, turns out I'm Acadian" realisation is common, particularly for Louisiana applicants and for some New England families whose ancestors arrived in Massachusetts via Halifax in the 1750s during the Deportation.

The clarifying questions:

  • What was the family's earliest documented North American location? Quebec villages → Quebecois lineage. Nova Scotia, New Brunswick, or PEI villages → Acadian or Cape Breton Scots lineage.
  • What surnames are in the family tree? Surnames on the Acadian list above point to Acadian heritage; surnames on the Quebec list point to Quebecois heritage.
  • Where did the family attend church? Acadians were Catholic; Cape Breton Scots Presbyterian; Loyalists Anglican.

Once you've identified the Maritime origin, the research workflow is similar to the Quebec one but uses different archives. The Tracing Canadian ancestry guide covers the universal tools (FamilySearch, Ancestry, MyHeritage, DNA); this article fills in the Maritime-specific gaps.
