No, I wish I knew, Joe. The 1850 Panola Co. MS Census (North, District 13, p340) does have a "Susan J. Sanders, age 15" -- ?possibly George's sister? -- living with George and Elizabeth (Yancey). Now, If we could find a marriage license for her... <smile>.
By the way, my grandparents were Ollie Jesse and Gertrude (Martin) Sanders. My mother speaks highly of your dad and grandfather <smile>
