That is my submission to find-a-grave. It was based on what information I knew at the time. It may have been pre-mature. Since learning of the hospitals being evacuated from Chattanooga to the Atlanta area, and specifically Academy Hospital to Marietta...I revisited Wyatt's files and now I am not 100% that he died in Chattanooga. It all depends on when Dr. Stout evacuated the Academy hospital and when it was set up in Marietta. It is very possible that this happened before August 20, 1863 and that Wyatt died in Marietta. If I learned anything the last several years....everything is not as "records" indicate them to be, especially rerecorded snipits from other sources, such as CMSRs.
Your note about JWW Ala CSA at Marietta Confederate Cemetery is in the least, a lead to go on.
I appreciate your assistance.
