Hi, my name is Joan DaMour and recently read a book written bay Walter Hornstein and Mary Colburn Hornstein. I got it on library loan from Northern Michigan University. "The D'Amour Family in Canada and Other Pioneer Families of New France." They are from Garden, Mi. in the Upper Pennsiula. It was very interesting for me. I learned much about Mathieu in Que. and was able to take my father back to Que. and I believe to France.
Marchand-Marchant tree is also very very good.
Tere is another book with almost the same Title written by a Monseignor Charles O'Neil D'Amour, Dominican order, of Delta, Mi. But I have not found it yet. I live in Livonia, Mich. Mr. Hornstein has a lot on the net. Good Luck Joan
