I'm so glad I have information that will help you. Just in the past few years, I've begun to search into my past. While my father's family is giving me some trouble, my mother's Bourdeau family is well documented. I guess the Canadians/French loved to keep good records. Anyway, this is what I've got. I'm researching from the Bourdeau ancestry, so I'm not sure if all these connections will be helpful to you. If your research is stemming from a Patenaude, than I guess this won't help fill in other gaps.
