Other than Charlie Hicks and the vet from the SC regiment, what GA resident is your third candidate?

Josiah J. Henderson of Jones County signed up to go to the 1938 Gettysburg Reunion,
but he backed out at the last minute due to illness. He was in the 45th GA, and was
present for the Gettysburg battle in 1863.

At the park service library @Gettysburg they have a signed registry with all the veterans
that attended the 1938 Reunion. I think it was the basis for the 1950 book of names
you previously mentioned.

Best Regards,

Greg
