You have the wrong Tannie L. Allison for Rosie's mom. Try this instead: 20 Aug 1887 - 22 Nov 1931 with death in Mitchell County. Reportedly, her sire was J. M. Chapel? Look for an offline email from me regarding that. Regardless, view 1900 San Saba-Precinct 1-District 130-Image 57 for J. C. Kimmons as head-of-household with Tannie Chapple age 14.
