Remember the brick wall? I hit it.John Henry Anderson is part Indian and Margaret is prob. full blood. They are eitherChoctaw or Cherokee or both. My grandfather, their son, is William Walter Anderson, born 1901,m. Dannie Pendergrass. His s.s. app. lists him as Indian but not what tribe. Siblings are Lula Mae, Mary Sue, William Thomas, Mckinley?, and Lon?. I found Lula Mae on 1910 U.S.census also listed as Indian but no tribe name.
