Great grandfather Pvt. Vernon H. Lockley was in Co.A and,I believe,died from disease near Vicksburg in 1863....his record shows him on detached duty herding beeves in March,1863,but nothing after that...I can't locate his name in any cemeteries even though he was supposedly buried in Warren County,Miss....Where can I search so I can find closure? Anything help would be greatly appreciated.
