I have been trying to locate parents/siblings/resting place of my GGG-Grandfather, Albert G. Clay, b NC or VA 1806, later residing in VA & KY. Somervell County, TX 1880 census lists Albert, 2nd wife (Susan Patten Salmons), & her son John Salmons. Cooke County, TX 1880 census lists Albert's son Rufus McCoy Clay & his family. Rufus later moved to OK & OR, but I've lost Albert. I have no beginning or ending for Albert. Can you help? Thanks!
