Unfortunately, I'm almost positive they don't. There's quite a bit of documentation and family history on William, and he appears to have been Waitsell (sp?) Prestwood's son. I did find his bond :)
Their two younger sisters and younger brother were all born out of wedlock too. I wish I had anything more than my imagination to figure out how someone in the late 1800s ends up with 5 kids out of wedlock from potentially two or more different fathers. The amount of DNA in common with my DNA matches makes me think at least 3 different fathers, but who knows.
