Also thought of this, we have ARW papers (requesting a pension) by William PRINGLE in which he states that his father was John PRINGLE. This would have been the William who I think is the first William (husband of Mary MCCOY), father of William who md. Elizabeth MCCOY. It does not tell us the wife's name, John's location, etc. just his name as the father of William. It's a piece of great info, but it has not helped me either!
