Re: Elias Sharp, Orange County, VA m. Margaret Proctor

There are 128 entries in the Rootweb WorldConnect for John Parks which give as his wife Mary Sharp.They state that Mary Sharp was the daughter of Elias (sometimes Elisha) Sharp and Margaret Proctor.

Most of them give precise dates for birth as 10 May 1706 in Essex County, VA, for John, and 26 Aug 1715, in King George County for Mary.

Can anyone provide proof that

(1) The Mary who was the wife of John Parks was born Mary Sharp?

(2)That, if Mary Sharp, she was the daughter of Elias/Elisha Sharp and Margaret Proctor?

The only "source" found so far is a general reference to a book on the Cheek Family.
