Can anyone tell me if this Marietta Confedate Cemetery is different than Stonewall cemetery in the same area?

I have one great grandfather in Stonewall (Larkin A. Jordan) around Marietta and supposively another great grandfather (Jackson W. or M. Brewer) in anpther unknown cemetery around the same area of GA. Both having died during the war from measles and smallpox.

Thanks,

Allen
