Are you by any chance related to Sylvester J Farmer? He raised Co. D, 15th Ga. Infantry, in Crawfordville, and served as its Captain until summer '62, when he was appointed Surgeon of the 15th, his pre war profession. I know little else about him, but have located him postwar, living in the Atlanta area.
I am researching Capt Farmer's brigade (Toombs's, later Benning's); if you have anything on him, please contact me directly. If not, good luck with your further research and let me know if your research ever wanders into my bailiwick, where I might assist you
best regards,
Andrew Johnson
