Marguerite Coutenais, my ancestor, is one of my "brick walls."

"Surname" in various records is Coutenais, Coutenaie, Kootenet, and Sauvage. Sauvage merely indicates native. The others show that she was from the Ktunaxa tribe (NOT daughter of David Frappier as some have suggested). Someone alleged that her marriage to voyageur Pierre Groleau was in Winnipeg and that the record had been destroyed.
