Sorry no I dont know. Some if the Tillmans went Parish Ar with Boykins then to California.Do you have Rowena family on Choctaw Roll. If not go to Rootsweb then have link for rolls you can find them there or Ancestry also have link to Choctaw roll. If you need links let me know. I do alot of Indian genealogy.
This findagrave is pretty helpful. Good luck Linda
