A John Gibson signed the will of John Stephenson of Bullocks Creek in what is now York Co,SC in 1773. He signed the will John "X" Gibson. I have seen a John Gibson married to an Agnes Adair. A few miles away was a David Stephenson on Turkey Creek in York Co,SC. He died in 1790 in the home of his daughter Anne Adair. Could the John Gibson who married Agnes Adair have been the John Gibson who signed the will of John Stephenson on Bullocks Creek in York?
