If this is the correct line, then Pierre Levesque entered the US in 1847 and married Lydia A Burns who was from "English Canada." She and Peter were my g-grandparents who had many children, one of whom was Lydia Ann Bishop,my grandmother. I have no idea when her mother, Lydia Burns, came to the US. She died in Kingman, ME in 1912.
I know something of Pierre's ancestry, and would be glad to share. I know nothing of Lydia A Burns' ancestry, and would appreciate info.
