I believe it high unlikley that the William who died in 1818 and was the ancestor of Sharon Young Jebavy was born in 1720 and was the son of John and Annie Young. If that was the case he would have been having his youngest children around age 80. That is just implausable to me. He didn't start having children till 1763, so a birthdate in the 1730's or early 40's would be more logical. He owned land in 1756, which would indicate that he was born before 1736 or for certain before 1741. We do know that his DNA matches the early Young familial line in Orange/Augusta Co., Virginia. It is my theory that he was either the son of Hugh who did not leave a will or James of Beverly Manor and Borden respectively. All of this is only theory!
