It is possible that someone may have specific info, but otherwise you will have to do the research. You may be able to get birth dates from the death records-- you can get them from the County as on the links to the Houghton County site. French-Canadians are in general very easy to research -- see the great link on French-Canadian research in Houghton County done by John DuLong, linked from main page. If you have the names of the grandparents who were married in Quebec with maiden name of mother, you can find a Loiselle marriage index somewhere, including through the LDS, to find their marriage (and their parents' names).
