Another random bit of info I ran across:
Alabama Civil War Service Database
http://www.archives.state.al.us/civilwar/soldier.cfm?id=29677
There are two records for this man, one under John Cato and one under John D. Cato.
John Cato
born 6-1-1847 SC Chesterfield
enlistment date: 1862/09/00 private SC Chesterfield District
discharge date: 1865/04/28 Camden SC
Regimental Unit: Brown SC Battalion Company C
Address: 1907-1908: Bradleyton RFD #1, Alabama

I think this is John D. Cato, son of Green Cato of SC --from the Needham Cato of SC line.
