Joseph Vanier would also be my great grandfather. It appears the native american did indeed come through Rose (Rosina?)Vincent. According to a copy of a certificate of birth and baptism from St. Francis Xavier Mission of Kahnawake (Caughnawaga), Que., Rose (Rosina-1874) would be the daughter of Louis Tekenistakwen (other spellings - Tekanatakwan, Tekenistchkuan) alias Rinfret, and Odile (Odelle) Viau. The next bit of information I have is actually from Louis Vincent (Rose's brother), per Father Paul M. Prud'homme. According to a statement in a sworn document, the said priest was told by Louis Rinfret-Vincent that "he was raised by his grandmother Viau. Later on, while in his teens, he came to the vicinity of Cheboygan, MI, and lived with a Vincent family, some Iroquois relatives on his mother's side, who had moved from Caughnawaga, and he went by the name of Vincent." According to another document, the name Vincent was his father's name on his mother's side. According to another certificate of Birth and Baptism from St. Francis Xavier Mission, Rose's father Louis Tekenistakwen was born March 30th 1850 to Thomas Oronhiawente(sp?) Rinfret and Marie Sophie Kasennakennhas Denaut, who were married @ the same mission church on 19 February 1849.
