Lt. W. B. Bateman of Co. A, 19th GA Regiment is shown as being buried in Grave No. 4 of Lot 851 at Laurel Grove North Cemetery. I have found this list is not 100% correct, so he may have been a corporal instead of a lieutenant. I'll look to see if your man's marker is shown in any of the many pictures I took there not too long ago. I'll let you know if I find one.
