17th and 18th Century Quebec French Genealogy
The PRDH is a database of genealogical information that is an "exhaustive reconstruction of the population of Quebec from the beginnings of French colonization in the seventeenth century" brought to us by the Université de Montréal.
When searching, be aware of the spellings of surnames. Depending on who recorded the name, the spelling might be off. As an example, Gauthier as compared to Gautier, Gaultier, makes quite a difference in your research. Be sure to try mother's surnames as well since you could find some children under one spelling and others under a different spelling.
