I am looking for my ggrandfather Henry Roark. He enlisted Nov.1861 in Ar, injured at Ft. Donelson, Tn and was taken to Nashville, Tn. I lose track of him there. I was wondering if anyone knows of a site that lists hopitals and names of patients. I assume he died. He doesn't show up in any census after that time. No pension was filed by his widow and can't seem to locate his name in any veteran cementeries. Any suggestions would be appreciated.
