What you have said about Dabney Pettus is very interesting. It supports what I have (but I'm afraid I don't know where I got the information.)I have that John Dabney Pettus m. Elizabeth Anne Overton in 1703 at Yorktown, Pennsylvania.I have that John Dabney was the son of John Pettus Sr (I don't have a wife) who was the son of Col Thomas Pettus and Elizabeth Mouring.NONE of what I have is substantiated. Only something to go on.I have John Sr.'s brother Thomas marrying an Elizabeth Dabney. They had a son named Dabney.
I too am very confused because I don't know which David Walker Pettus I belong to!!! My great grandmother was Margaret Pettus Hughes.
