Jeff, What information I have does not show your ancestor.
I would try contacting CPT. Todd Carter SCV Camp #854 there email adress is glima@tnema.org. They take care of several cemeteries in the area that were formed in and around the Battle of Franklin including the McGavock Cemetery. I would also try contacting Sam Davis SCV Camp #1293 at sdc1293@bellsouth.net. These to camps are actively involved in recording and preserving our ancestors final rest place.
