Fédération des familles souches du Québec
The Fédération des familles souches du Québec or FFSQ is a "non-profit organization dedicated to giving a unified voice to Québec’s family associations. It defends their collective interests before private and public authorities" amongst other goals. They offer a newsletter, library, and links to all their member family associations, like the Association des Gauthier d'Amérique Inc. which is how I learned about the group and all they have to offer.
Research is most easily done through their links and publications in French, so if you need some help with translation, don't forget the online translation (machine translation only) available at Google translate.
