Seeing as how there were several Murphree/Foust marriages plus, I believe Foust/Bynum marriages, it points strongly to these Foust all being related and of course all these Murphrees are related.Fowlers are also mixed up in the group.
It also points to James Murphree b. abt.1799-1800 in SC being the son of William Murphree, Jr. b. abt 1769 NC and Sarah "Sally" Linn, as we know most of these also ended up in Blount Co.
The other one, would be Levi Murphree, who had a son, Caleb b. abt. 1796.It's possible there was a son born about 1800-1801, that no one is aware of.Most of Levi's sons didn't come to Blount Co., the only one I'm aware of was Caleb who married Martha "Patsy" Bynum.
It's possible that Caleb was not Levi's son, but instead William Murphree, Jr's son, and someone in the past put him with the wrong parents.As several of William Murphree Jr's sons did end up in Blount County.
I'm still piecing the tree back together as I lost the vast majority when my desktop crashed and the only backup which would open or wasn't corrupted was from 2005.
