I know nothing about this couple other than what I stated. I have been trying to find out info on them. Her parents are Andrew and Prudence Livingston who lived in what is now Adams Co. I know nothing about William. I don't know the religion because most of the early non-German (they are not German) records did not survive. I don't know if they stayed in Adams Co. area or not. Her father died intestate in 1777. I have been there to research and found nothing on them, some on William Thompsons but nothing to indicate any of them were married to a Mary Livingston. I suspect they were born 1740-1750. I don't have dates on her parents either. Quite a challenging search. Paula
