I highlight this family because the names Susannah and Rachel are important in it, as well as John.It's possible we descend from Richard, Robert, Charles, or William Hill.I'm not sure of John Hill and Susannah Clarke's other sons survived childhood.Just tossing that idea out there.
The most definitive yes-or-no answer to the Isaac Hill theory would be in the will of Isaac Hill or of Margaret Jennings, who might have married Josias Randle/Randall/Randolph in her widowhood...in which case, the will of Josias Randle could also show us the answer.Not either of these ever made a will, though, or if such wills survived the fire.
