Does anyone have any information about a Civil War unit called "Florida 1st Reserves"? My husband's ggg grandfather, William Mathews, was taken prision during the Battle of Marianna. I have followed the trail through the various prison camps where he was sent, ending up in Elmira Prison Camp, Elmira, New York where he died in December, 1864. Each reference I have located for him states his unit as "Florida 1st Reserves", yet I have been unable to locate any information on a unit by this name. Any help or suggestions would me greatly appreciated. Susan Mathews
