Somebody's been screwing with the Custises and they're getting all messed up.
Col. Argall Yeardley married Ann Custis, daughter of Henry Custis and Joan Whittington (widow), circa 1649 at Rotterdam, Holland.
John Custis I and Joane Smithier had NO. CHILDREN. (that the Miles Files know of, which means if there *were* any, they never came to America).
(And John Custis II was Ann Custis' brother - he was NOT the son of John Custis I.)
