How to Research Your Quebec Ancestry
Quebec has the most complete pre-industrial demographic record on Earth. If your ancestors came from French Canada, the paper trail is extraordinary — and most of it is accessible from your living room. This guide explains where to look, what you will find, and how to avoid the most common mistakes.
I. The Quebec Advantage
Most people who attempt genealogy hit a wall within a few generations. Parish registers were lost to fire, war, or neglect. Civil registration began late. Records were kept in languages or scripts that modern researchers cannot read. For most of the world, tracing a family line past 1800 requires luck.
Quebec is different. The Catholic Church in New France kept meticulous records from the very beginning. Parish registers of baptisms, marriages, and burials begin in 1621 and run continuously to the present — over four hundred years of unbroken documentation. This is not an accident. French colonial law required it. The Coutume de Paris mandated that priests record every sacrament in duplicate: one copy for the parish, one for the civil authorities. The result is a redundant archive that survived everything the centuries could throw at it.
Beyond the parish registers, Quebec preserves an extraordinary notarial archive. Every marriage contract, land sale, estate inventory, apprenticeship agreement, and guardianship arrangement was recorded by a notary and filed with the courts. These documents reveal not just who your ancestors were, but what they owned, what they owed, and how they lived.
Three nominal censuses — conducted in 1666, 1667, and 1681 — recorded every person in the colony by name, age, occupation, and household composition. The 1666 census was the first in North America. These three documents together provide a near-complete snapshot of every French settler in the St. Lawrence Valley during the colony’s formative decades.
The practical consequence is this: if your ancestors were in Quebec before 1850, you can almost certainly trace them back to their arrival from France. Many lines go back to the 1620s and 1630s — fifteen or sixteen generations. No other population in the Americas has records this complete for this long.
II. Primary Sources
Six databases and archives cover nearly everything you need. Each has different strengths, coverage periods, and costs.
1. PRDH (Programme de recherche en démographie historique)
prdh-igd.comWhat it is: A University of Montreal project that has been digitizing and cross-linking every Quebec parish record from 1621 to 1849. This is the gold standard for early Quebec genealogy.
What it contains: Approximately 1.7 million individual records, including baptisms, marriages, and burials. The key feature is family reconstruction — the PRDH team has linked individual records into family units, so you can follow a couple from marriage through all their children’s baptisms to their burials.
Access & cost: Subscription-based, approximately $100 per year for full access. Worth it if you are doing serious research. The linked family reconstructions alone save hundreds of hours of manual cross-referencing.
Best for: Systematic lineage tracing, linked family reconstructions, and finding all children of a couple. If you want to build a complete tree rather than trace a single line, PRDH is indispensable.
2. Nos Origines
nosorigines.qc.caWhat it is: A free, community-sourced genealogy database focused on Quebec families. Think of it as a collaborative family tree built by thousands of contributors over decades.
What it contains: Marriage records, baptism dates, death dates, and parent-child links for hundreds of thousands of Quebec individuals, many traced back to the earliest settlers. Each individual has a permanent ID (PID) that you can use to reference and share specific records.
Access & cost: Completely free. No subscription required. This makes it the best starting point for any Quebec research project.
Caveat: Because it is community-sourced, errors exist. Dates may be approximate. Parent-child links are sometimes wrong, especially in the earliest generations. Use it for initial discovery, then verify against PRDH or Drouin for anything you intend to publish or rely on.
Best for: Free initial lookups, finding marriage and baptism dates quickly, and getting an overview of a family line before investing in paid sources.
3. Drouin Institute
drouin.comWhat it is: A private archive that microfilmed the original parish registers of Quebec, Acadia, Ontario, and parts of New England. Joseph Drouin began photographing parish registers in the 1940s. The collection now covers millions of records.
What it contains: Digitized images of the original handwritten parish entries — baptisms, marriages, and burials written in iron gall ink on rag paper by the parish priest. You are looking at the actual document, not a transcription.
Access & cost: Subscription-based. Some Drouin records are also available through Ancestry.com with a World Explorer subscription.
Best for: Seeing original documents, verifying transcriptions, resolving discrepancies between databases, and finding details (witnesses, signatures, marginal notes) that do not appear in transcribed databases.
4. BAnQ (Bibliothèque et Archives nationales du Québec)
banq.qc.caWhat it is: The provincial archives of Quebec. BAnQ holds the original records that the church and courts deposited with the civil authorities — the second copy mandated by the Coutume de Paris.
What it contains: Parish registers (the civil deposit copies), notarial records, census documents, newspapers, maps, photographs, and court records. The Pistard database indexes the notarial collection.
Access & cost: Free digital access for many collections. The physical archives are in Montreal and Quebec City. Remote access to digitized notarial records is increasingly available.
Best for: Marriage contracts, land concessions, estate inventories (inventaires après décès), tutorship documents, and any notarial record. These documents tell you what your ancestors owned, what debts they carried, and how they divided property among their children.
5. Library and Archives Canada (LAC)
bac-lac.gc.caWhat it is: The federal archives of Canada. LAC holds records created by or submitted to the federal government, including census records, immigration documents, military service files, and land grants.
What it contains: Federal census records from 1851 to 1931. Immigration records, passenger lists, military service records, and land patents. Also holds the colonial-era records of New France transferred from French archives.
Access & cost: Free online access for digitized collections. Physical archives in Ottawa.
Best for: Census records (1851–1921), which provide household snapshots every ten years. Also useful for immigration records if your ancestors crossed the border to the United States and later returned, or for military records from the World Wars.
6. FamilySearch
familysearch.orgWhat it is: A free genealogy platform run by the Church of Jesus Christ of Latter-day Saints. The LDS church has been microfilming records worldwide since the 1930s, and their Quebec collection is substantial.
What it contains: Digitized images of many Quebec parish registers, some census records, and user-submitted family trees. The image collection overlaps significantly with Drouin but is free to access.
Access & cost: Completely free. Create an account and browse. Some record images require visiting a FamilySearch Center (local LDS family history libraries) due to licensing restrictions.
Best for: Browsing original register images at no cost. If you cannot afford a Drouin or PRDH subscription, FamilySearch is your best free alternative for viewing actual document images rather than transcriptions.
III. Getting Started
A step-by-step approach for someone beginning from scratch.
Start with what you know
Write down every name, date, and place you already have. Talk to older relatives. Look at old photographs, prayer cards, and family bibles. The goal is to establish your most recent generation with certainty before working backward. You need at least one name and an approximate date or place to begin searching archival records.
Find a marriage record
Marriage records are the skeleton key of Quebec genealogy. A typical Quebec marriage record names the bride, the groom, both sets of parents, and often the grandparents. One document gives you two generations. Find a marriage, and you can immediately jump back to the parents’ generation and search for their marriage, which names their parents. This chain can carry you back centuries in a single afternoon.
Use Nos Origines for free initial lookups
Go to nosorigines.qc.ca and search for the couple you found in step 2. If they are in the database, you will see their parents, and their parents’ parents, often back to the original immigrant ancestor. Record the PID numbers for each individual — these are your permanent reference links. Build a rough draft of your tree using Nos Origines before spending money on paid sources.
Verify with PRDH or Drouin
Nos Origines is community-sourced and contains errors. Before you trust any connection, verify it against a primary source. PRDH provides transcribed and linked records. Drouin provides images of the original handwritten entries. Ideally, check both. If a date or parent-child link appears in both Nos Origines and PRDH/Drouin, you can be confident it is correct.
Check census records for household context
The 1666, 1667, and 1681 censuses record every person in New France by name. For later periods, the federal censuses (1851–1921) provide household snapshots including ages, occupations, birthplaces, and sometimes religion and ethnicity. Census records do not prove parent-child relationships, but they confirm that the right people were in the right place at the right time.
Look for notarial records
Once you have the basic tree established, search for notarial records through BAnQ’s Pistard database. Marriage contracts list dowries and property. Estate inventories (inventaires après décès) list every object in the house — furniture, tools, livestock, debts, clothing. Land concession documents show when and where your ancestors received their first farm. These records transform names and dates into real lives.
IV. Common Pitfalls
Mistakes that trip up even experienced researchers.
Name spelling varies wildly
There was no standardized spelling in New France. Priests wrote names as they heard them, and different priests heard differently. The same person might appear as Baudouin, Beaudoin, Bodoin, or Bodonin in different records. Fièvre appears as Fraire, Fiebvre, Fèvre, and Lefebvre. When searching, try every plausible spelling variant. If a search turns up nothing, the name may simply be spelled differently in the index.
Ages in censuses are often wrong
Census takers estimated ages, and people often did not know their own exact birth year. Noël Morin, whose baptism record shows he was born in 1621, is listed in the 1681 census as being 38 years old — he was actually about 60. Use census ages as rough guides, not definitive evidence. Always prefer baptism records over census ages.
“Dit” names are not errors
Many Quebec families had both a surname and a “dit” (also called) name. A man might be recorded as “Pierre Blouin dit Laviolette” in one register and simply “Pierre Laviolette” in the next. Some families eventually dropped the original surname and kept only the dit name, or vice versa. The dit name could indicate a military nickname, a geographic origin, a physical trait, or a family branch. When searching, always check both the surname and the dit name.
GEDCOM files are hypotheses, not sources
Family trees downloaded from Ancestry.com, MyHeritage, or other platforms are user-submitted and frequently contain errors. A GEDCOM file is someone’s hypothesis about who is related to whom. It is not evidence. Common problems include duplicate individuals merged incorrectly, children assigned to the wrong parents, and dates copied from other user trees without verification. Treat every GEDCOM claim as a lead to be investigated, not a fact to be recorded. Verify against original parish registers before adding anyone to your tree.
Multiple people with the same name
Quebec families reused names constantly. If a child died in infancy, the next child of the same sex often received the same name. It is common to find two or three “Jean” or “Marie” children baptized to the same parents over a span of years. When you find a baptism, check whether there is an earlier burial of a child with the same name in the same family. Confusing two same-named siblings is one of the most common ways a tree goes wrong.
Second and third marriages
Death rates in New France were high, and remarriage was fast — often within months. A woman who appears as “Marie Couillard, wife of Guillaume Fournier” in one record may appear as “Marie Couillard, widow of Guillaume Fournier, wife of Jacques Miville” in another. If you trace a line through a woman, make sure you are identifying the correct husband for each marriage. Check whether she married more than once.
V. Methodology Used on This Site
Every ancestor listed on this site was verified using a dual-source methodology. Each individual was checked against at least one of two independent primary sources: Nos Origines (the PRDH-linked community database at the Université de Montréal) and the Drouin Institute (digitized original parish registers). Many ancestors are confirmed by both.
This dual-source approach ensures that no claim rests on a single database or a single family tree. When Nos Origines and Drouin agree on a parent-child link, the probability of error is very low. When they disagree, the discrepancy is noted and investigated further.
