Just happen to be at the NARA in DC today and did a search on the Confederate Dead who died at the York, Pennsylvania hospital after the battle of Gettysburg. According to records the dead at the York hospital were taken South to Richmond, Virginia and buried in a mass grave at Hollywood Cemetery.

I did not realize the UDC went to various hospitals around Gettysburg to gather their dead. William J. Wiley of Walton County, Georgia is one of those in a mass burial in Richmond, Virginia.
