Hi: I just got a reply to a query on a mailing list and there was a copy of the marriage in Bathurst. Hard to read but I think they were married 26th of August 1844 and it was registered the 11 Dec 1844. No mother's names but he was the son of Jean Baptiste Chamberlain an she was the daughter of Jean Fournier. Louis Lagasse and Anore Fournier were witnesses. Maybe that will help to find the right family for Francoise. By the way she was listed as Francis on the document.
