It looks like you are correct. William Henry couldn't have been the guardian on that date. I didn't have the date of the guardianship. I just knew that it was said to be a guardianship.
I'm related from the Salley side of the family. Ann Salley is my 1st cousin 5 times removed. Most of my information came from the Salley information. I just started working on the Pendarvis side, so I'm not sure about alot of the Pendarvis information. There seems to be alot of different tales. Anyway, here is what I have on William A. and William Henry being cousins.
James Pendarvis(1774-1782) and William Pendarvis(1775-1784)were brothers. Their sons William Henry Pendarvis and James Washington, Sr. were 1st cousins. Their sons William A. and William Henry would be second cousins.
Also Message #158 from Randy Floyd on this forum, states almost the same information that I received from the Salley side of the family. Here is what Randy wrote.
