I have a Margaret Bourassa married to a Ducamp which could be a Ducharme mispelled. Margaret is the daughter of Louis Bourassa, Sr married to Mary Bois/Chickanogekwe on 24 January 1807 on Mackinac Island, MI. They had 11 children of which a Jean Baptiste was born 20 February 1817 thus questioning the birth year of Margaret unless they were twins. Menominee is not far from Mackinac Island. I also have Mary Bois as possibly from the Ottawa Tribe.
