I have info on this couple in my database. Joseph George Dupont was born 11 Dec 1827 in Vercheres, Quebec. He and Angeline married 3 Feb 1859 in Osseo, Hennepin Co., MN. I have a list of their children if you would like that. I only have marriage info on two of them -- Emma Rosetta and Joseph.
Let me know what info you need. We do not descend from this line but from a sister of Joseph George. Did you also know that he was married twice? His first wife was Dominique Chagnon.
