I've found with these old cemetery records you need to really be "open-minded" and look for "close" instead of exact matches. My soldier who is buried there should be "A.R. Wigginton" with the 60th GA but the list shows him as "A.K. Higgleton" with the 6th GA. The dates match up well so I believe this to be my soldier.

Your search, obviously, is more complicated because of your Johnson name, but I would say that you found your soldier. Enjoy the search!
