Briscoe Parrish - Sons Named John

Briscoe has two sons named John connected:

John Reuben Parrish

born circa 1750
Stokesdale, Guilford, North Carolina,

and

John Eaton Parrish

born January 22, 1773
Rockingham County, North Carolina

Neither has a wife or children connected

I'm working thru a DNA cousin's tree on Ancestry and she has her lineage back to Briscoe via a son named John whose info is:

John Parrish
B:1755 Goochland, Goochland, Virginia, United States
D:1810 Greenville, Greenville, South Carolina, United States

that John was married to
Elizabeth Durant
B:1756 North Carolina, United States
D:1844 Warren, Georgia, United States

None of the three Johns have matching details. I doubt Briscoe had 2 or 3 sons named John, and I have no idea what info is correct. Just sharing since when I came to Geni to search for info on the John who was married to Elizabeth Durant, I discovered his supposed parents already have two other sons named John connected to them.
