My great grandfather, John Machaney Stone, married Mary Ann Compton, b Sep 25, 1831. She was the daughter of a Reuben Compton who married Nancy (last name unknown). They lived in Pittsylvania, Va. Could these be the same Comptons you are searching for. Reuben and Nancy had at least 6 other children, Termilia, John, Tabitha, James, Joshua, Lafayette and Rueben Jr.
Please respond if you have additional info about these Comptons.
