No, I am not updating any of my Eaves information. I took my best shot at it and have now gone on to other ancestors.
And no, I have not found any ancestor earlier than William Eves. There was certainly one or more John Eaves in Virginia in the 17th century, but I still have found no information that connects any of them to William Eves.
Other people claim that William was descended from "Jonathan" Eves, as the beginning of my book says. I think that probably the abbreviation "Jon." probably referred to a John. As nearly as I can tell, the assumption is based solely on the fact that the John Eves or Jonathan Eves who were transported to Virginia had the same surname as William Eves.
But the Eaves Family Association has been doing a DNA study, which indicates three separate Eves/Eaves lines. And two of them were in North Carolina at the same time.
