I'm not sure if I contacted you before or not. George Ira Neal and Della Willingham were certainly cousins of some degree. George's ancestry included Troy Griffin and Martha Willingham. I don't know about Della. Since she was born after the 1880 census, I can't place her without knowing who her father was. Maybe you can tell me.
