Thanks for the response. I believe that this is the Nathalie I've been looking for. She married Jean Baptiste Gosselin on 15 Oct 1844 in Ste. Rosalie, Bagot, Quebec. I only have information about one of their children, a son named Remi Gosselin, my great grandfather. Remi was born on 23 Apr 1852 in Ste. Rosalie and died on 15 Jun 1941 in St. Malo, Manitoba. He married Eleanor Vertefeuille in Ste. Rosalie on 5 Apr 1874. They had 14 children.
Any information you can give about Nathalie and her parents will be greatly appreciated. I know nothing about her except the date and place of her marriage.
