Thanks so much for responding. My dad and I are researching the family tree on his side. The last name is St.Sauveur which turns out to be the dit name for Domine. So far we have been able to get us back to Pierre Henri Domine who married Madeleine LaForest. He is thought to be our original ancester in Quebec possibly Canada. We have reviewed Tanguay and have verified some things with letters from Dad's deceased aunt. Now we are having a devil of a time going back to previous generations. He has been working at the library of Latter Day Saints and I am working through French Canadian Geneaology societies. Perhaps the site you are talking about would help us. We look forward to your invite.
