I don't know how much help I will be, but our two family trees graze one another. Our shared person is Jettie Lemmon. She married Walter Scott "Tobe" Pitts. Mr. Pitts had previously been married to Mabel Garrett, until her untimely death in 1908. Mable is my 2x great aunt.
Prior to Jettie and Tobe getting married, she was married to Connie Turnbull. They had at least 2 sons: Clarence and Loyd. Clarence died at the age of 31 in 1933. Clarence, his bother, and father are listed on the U.S., Native American Enrollment Cards for the Five Civilized Tribes, with the Tribal Affiliation of "Chickasaw By Blood".
You posted this some time back. I would love to compare notes.
