I am looking for the mother of William BULLITT who was born in Virginia c. 1750. William is mentioned in the will (Fauquier Co., Virginia) of his father, Benjamin BULLITT, Dated 3 May 1766 as "William BURDITT (alias BULLITT)". William married Mary BURBRIDGE before 1777, but I have no place or exact date for the marriage. Any clues about William's mother and documented birth/wedding dates would be greatly appreciated. Thanks.
