My mother swore that she was 1/16th Indian as did all her brothers & sisters. Her grandmother was Marguerite Gamache who married Barnabe Boutin October 19, 1858 @ St. Cyrien de Levy of Napierville. Marguerite Gamache was born November 23, 1843 @ Napierville. Her parents were David Gamache & Cecile Giroux. Don't know if this connects to your Gamaches. In all my research, this Indian heritage has always pointed to the Gamache family. However, I have not been able to prove it.
