I've put what I have on this family on the WorldConnect Project at http://www.rootsweb.com
. This link will take you straight to the data base.http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?db=demarce2
Just search on the name you're interested in and you should find it.
My husband isn't directly related to the family you mention, but I looked up all the French Canadians in the Dead Lake Prairie settlement in Waterville Twp.
