I had a Gr-Gr-Gr uncle, Josiah Tyson, who also served in Co.F, Fannings 1st Georgia Reserves with his two teenage sons, Jonah and John D. Tyson. They were from Carroll County, Georgia also.
They all 3 became prison guards at Andersonville. Jonah was listed as "died at Camp Sumter of disease in 1864." Sounds like the camp guard didn't fare much better than the prisoners.
I went to Andersonville last summer, and as I walked around the stockade site, it felt like someone was following me the entire time. I never could shake that feeling the whole time I walked around the site. It was almost unnerving. Made the hairs on the back of my neck stand up! I swear you could just feel the suffering in the air. I've been to other Civil War sites and never got that kind of feeling as I did there. If there is such a thing as a haunted place, Andersonville is that place.
