I am a part of the Gamache family and I too was told there was Indian blood in our huge family but that would be way back in the 1700's . It was told to me that Jean Baptiste came down the Mississippi from Quebec(originatly from France ) and stoped at St Louis Mo to found the town .
After that he was south bound and found an Indian girl and married her ... later he suposidly left her behind with a child or two and was on his way To Ste Genevieve Mo.
At what time in history did you hear of an Indian girl ?
St Louis Mo
