3. PRDH Online
The PRDH, or Le Programme de Recherche en Démographie Historique, at the University of Montreal has created a huge database, or population register, encompassing the majority of individuals of European ancestry residing in Quebec through about 1799. This database of baptism, marriage and burial certificates, plus biographical data and records extracted from early censuses, marriage contracts, confirmations, hospital sick lists, naturalizations, marriage annulments, and more, is the most comprehensive single database of early French-Canadian family history in the world. Databases and limited results are free, although there is a fee for complete access.
One of the major published sources for early French-Canadian genealogy, the Dictionnaire Genealogique des Familles Canadiennes is a seven-volume work of the genealogies of early French-Canadian families published by Rev. Cyprian Tanguay in the late 1800s. It's material begins about 1608 and extends to material at and shortly after the Exile (1760+/-).
5. Loiselle Marriage Index (1640-1963)
This important resource for French-Canadian ancestry includes marriages from 520+ parishes in Québec and a few parishes outside Québec where there were large settlements of French Canadians), indexed by both bride and groom. Because the index entries also include parents' names for both parties, as well as the date and parish of marriage, it is a very helpful source for tracking French-Canadian families. Available on microfilm at the Family History Library, Family History Centers and many Canadian and Northern U.S. libraries with large genealogical collections.
