Thank you so much for the information. I can't be positive that William was a Union soldier. It's just the family story and is all I have to work on right now. Other activities of the family during the period 1861-1865 support the theory that he was away, probably at war.
John W. Wilburn b.1827 GA sounds promising enough for me to order his records. Thank you so much for your help!
Carol Wilburn Buck
