No information on that particular gentleman, but the 1st Georgia Reserves were one of four reserve units that were formed to free up the more seasoned, physically fitter guards for front line action. The Reserves tended to be made up of 16-18 year olds, and men over 50, and were reportedly poorly trained, poorly armed, and poorly fed. The guards suffered through both measles and typhoid epidemics in the summer of 1864, and I'm still trying to puzzle out just how many of them died because of diseases contracted at Andersonville - the best guess I've read in about 10%, but since many of them were close to home, they were sent home when they got sick and died there, but it's not clear how many of these "away" deaths were counted and how many weren't. There were about 116 or 117 guards buried at Andersonville, but they were dug up and moved to Americus when the authorities decided to build a wall around the National cemetery and leave the guards' section outside the wall, and allegedly untended.
By the fall of 1864 (when they started relocating the majority of the prisoners), desertion among the guards was such a problem that the Confederate Army was taking out ads in the Macon paper, offering a $30 reward for information leading to the recovery of a guard who was AWOL. So far we can't find any evidence that the guards were paid after December, 1864.
I can't come up with any evidence that the guards were given a 30 day furlough as a reward for shooting a prisoner inside the deadline - best guess is that this was something the guards told the prisoners to keep them in line, even though it wasn't true. They DID apparently get a 30 day furlough for each teenager they could get to join the reserves, and 20 days for each over 45 man that they could get to join
