I am very happy to receive your post. I had given up hope of hearing from anyone regarding this. Have you been able to find a legal name for the lady you refer to as Mya? Do you know if one of the descendants of Jean Baptiste Gamache and Mya had a child named Mary E. Williams? Her father's name was George, and I cannot read her mother's name. They are listed on the 1880 Census of Plattin Township, Jefferson County, Missouri. She was married to my great grandfather, John A. Vahey, in DeSoto, MO on 25 November 1885. We think this is our link, but cannot officially make the connection.
