In response to your query on Burke county page - The parents of William Riley YORK (1760 - 1832) were Thomas YORK and Elenor SILVER. The ancestry beyond that is not certain. We show his wife as Mary Ann WALBERT.
Walbert could have been her first husband. We also show William as married to a Catherine SMITH. Actually we do not know if he married her or even got divorced from Mary Ann. BTW, we visited that cemetery this summer. It is kept up by the state as it is in a state park, but the stones were unreadable. You can check my website at http://members.tripod.com/~lrnoah
