On the census rolls for CR Agency Mary comes in as sinconjuwin (burnt thigh woman) it is unknown if that was her name or if that was where she was from. her father is was listed as "Little Thunder" unfortunately i don't know what her mother's name was. I know that there is a LeBeau book or at least the Albert LeBeau Sr. line and in there talks about Jean-Baptiste, and Antoine and Mary. there is even a picture of her with antoine i think!
