I'm another of the VAUGHAN distant cousins, and am descended from Richard (1701) and his son Richard (1741). Richard (1741) had a son called Absolom (1772) who married Mary ??. I am descended from their daughter, Letitia. I've found what I think is a record of Absolom and Mary's marriage on the IGI at Staunton By Monmouth on 4 Oct 1803 - can anyone confirm this?
Also, Mary's surname is BENNETT and there is a reference on this board to Absolom's brother John (1777) marrying Elizabeth BENNETT in the same year (1803).
