I also have John as the supposed father of Willie Atkinson(1784-1857) who married Susannah Barnhill (1773-1859).
I have their children as:
Mary married Luke Sikes (my line)
Jane married James Holton
Ann married John G. Sutton
Willie Alford Elizabeth Susan Sutton
I've got more info on these lines, mostly on my line, if anyone needs it.
