In my case, it was this information that solved the mystery of why the wrong regiment was inscribed on some headstones.
The applicant, Mr. Tumlin, was a deacon of the church and clerk and caretaker of the church cemetery. In the late 1970's, he began submitting applications for headstones and I have found, so far, applications he submitted over the nest 5 years. It is obvious that he researched the records at the GA Archives for the men from the church who served in "Joe Brown's Army."
Tumlin correctly identified the service of each man, for example - PVT, Co. C, 2nd (Storey's) Regt Inf,
GA State Line.
HOWEVER, in the bottom left corner of the application in the area reserved for "Veterans Administration" notations, the regiment information from Mr. Tumlin was
changed to read: PVT, Co. C, 2nd Regt GA Inf. and this is what was inscribed on each headstone.
It is obvious that the people finalizing the applications did not know the difference in the two regiments.
It is interesting that Mr. Tumlin did not include birth and death dates on the applications found so far. This did not seem to matter because the application was processed. One of my ancestors for which Tumlin order a headstone died in TX in 1916 and is buried there. His father was the minister of the church for many years and I believe Tumlin included the headstone for that reason, maybe assuming he was buried there, or included it as a cenotaph. I'll never know for sure.
Also, some of the cards in this time period changed and no longer asked for the enlistment date. The numerous changes made to the cards over the years in very interesting.
@bdtex is so correct that this information is invaluable.
