John and Phebe Mathis Forman

Does anyone have this couple in their tree?
Could be Jonathan, too.
I found a Phebe Forman in Old Tennent Church Yard in Tennent, NJ. The John Forman marker was unreadable.
I only have these two names...no dates or locations.
John/Jonathan and Phebe Mathis Forman were parents of Mary Forman who married Joseph Smith Woodward in Lumberton, Burlington County, NJ, on 12 Mar 1811.
Mary was swimming near Tucker's Beach (location?) and Mary was carried out beyond her ability to swim back. Joseph rescued her and they married.
Both Joseph and Mary Forman Woodward are buried in Davenport, Scott, IA's Oakdale Memorial Gardens. They are on Find-a-Grave.
