Ed - I have done a little research on this Vaughan family and how they relate to the Woodgates, Polks and Smiths. The Edward Vaughan you reference was the son of Jonathan Vaughan of Chester Co., PA who was one of the owners of the Deep Creek Iron Works and Nanticoke Forge. His mother was Ann and her probate record should be in the same book you reference. Lisa Just Ed writes, "Also, I have run across an Edward Vaughan, Will made Jan. 10,1782 (listed p.141 Calender of Sussex Cty. Probate Records) Heirs: Bro. Joseph Vaughan; Sister Mary Polk; nephew Jonathan Vaughan Woodgate. Exec'r, Bro.-in-law William Polk. Estate settled Nov. 10,1791. At this time, I can not relate this person to the Vaughan tree as I know it."
