Elvin and Jane were my g'gparents. The 1880 Census was for non-whites only in Indian Territory, so there is no concrete record of their timeline from Clarksville, Red River, TX. They were in Burneyville, Love, OK along with their son Sanfrancisco and d-in-law, Roxilena "Roxie" Gannaway. I have quite a bit of info on Elvin and Jane's children. Their son, Sanford Augustus was my g'pa. Let me know if I can help.
