I've been working on the Ball line from Carter KY. I have William's middle initial as an "H" though. And I have that his father is Manford from VA. I recently found a marriage record for Manford Ball and Rachael Willbourne for 13 Dec. 1930 from VA (or WVA depending on who compiled the record). But I reach a dead end there. I haven't been able to confirm the spelling of Rachel's name (Rachael or Rachel) nor her middle name or the spelling of her last name (Wilburn or Wilborn or Willbourne) except for the marriage record where it does not look like she wrote the name there herself. I also have a record of William H. Ball marrying Lilley Anna Needham.
If you still visit this site or are working on this line, I would love to talk to you about it direct e-mail or on this forum. Please let me know.
