The marker here bears the name Charles E. Rice, but the man who is buried here is more of a mystery. First, despite what the marker says, it appears that the man's name was actually Columbus Eugene Rice, although it is noted in a 1913 article in the Tuscaloosa News that he went by the name Charlie. Secondly, while the grave is marked with the Southern Cross of Honor, it is unclear what unit Mr. Rice served in with the Confederacy. Confederate rosters list a Charles E. Rice as belonging to the Alabama State Artillery, although there is no information about that unit's history, while a Columbus E. Rice appears in both the 8th Regiment of the Confederate Cavalry and the 4th Battalion of Mississippi Cavalry. This could be explained by a unit consolidation due to losses as the war progressed, since the same person seems to have been a member of both units.
Records for both Charles E. Rice and Columbus E. "Charlie" Rice both show the same birthdate and nearly the same death date (my research shows January 12), so it seems highly likely that they are both the same individual.
According to the Tuscaloosa News article, Rice was a prominent businessman in Tuscaloosa after the war, and he served as a longtime mayor of Northport.
To locate the final, gather information from the grave marker for Charles E. Rice:
