I wanted to just throw this in for consideration. One of William Barker's male descendants did DNA testing for me and did not match any Barkers - so far. A Barker from the Surry County, VA Barkers and one from a group of Barkers who lived in Hanover County, VA were also tested and did not match our Barker. Of course, this could just mean that there was a break in the male line somewhere along the way, but we are still hoping to find a match.
