Parent-Proof notes for James (Spouse 1)
There is a deed whereby John Poteet mentioned several of this name including James and without studying things too much and needing a place to put James, I have guessed James was the son of John. According to the consensus of the Internet, John’s son James married Elizabeth Crabtree (that marriage recorded in 1748 in the St Johns/St Georges church records).
There also was a James Potee who with wife Elizabeth baptized four children at St Johns/St Georges in 1720, 1722, 1725 and 1728. I have guessed that he was Francis’s son although if Francis died before 1688, James was well into his thirties when he baptized these children.
It seems pretty clear they were two different James.
There is what seems to be a well researched book The Crabtrees of Southwest Virginia on Ancestry that traces descendants of the Crabtree family of St Johns/St Georges who moved to Virginia in the mid-1750’s accompanied by Elizabeth Crabtree and her husband James Poteet.
