The last card in this soldier’s CSR shows he was listed on a report of prisoners of war who died at 1st Division Hospital, 20th A. C., from December 24 to 31, 1864. It also shows he was captured on 24 Dec 1864, died on the 28th (not the 24th) and was buried in grave no. 9 of the Savannah Graveyard. A soldier identified as F. H. McKilly (no regiment given), who died on 28 Dec 1864, is shown as being buried in lot 921, grave 11 in the small booklet titled List of Confederate Soldiers, Interred in Soldiers’ Lots, Laurel Grove Cemetery, Savannah, Georgia (printed in 1874). I believe there is a good possibility that F. H. Mckilly is actually H. A. McKelvy. I have found many errors with identities of soldiers buried in this cemetery, which can be attributed to many different reasons. There are two Laurel Grove Cemeteries in Savannah. This particular one is known as Laurel Grove North. You may want to look up the cemetery's phone number and give them a call to see if they have any additional info on Mckilly.
