If I may answer for Steve, the answer is no.

Locations Steve Stacey described are related to Preston family homesites in Monroe County AL.

The Army of the Cumberland field hospital location would be inside Federal lines near Resaca GA. Its location would be long since lost to history as it probably consisted of tents and nothing else. It only existed for two or three weeks at most. No permanent markers would have been placed in a field hospital cemetery, only flat wooden slats at best. Shortly after the war ended, testimony that stake markers for Confederate dead at Franklin TN were being used for firewood.
