I have found what appears to be the discharge papers for my great grandfather Robert Parker but I have been unable to locate any info regarding his unit. The papers indicate that he enlisted on 8/24/1861 in Grenada, MS in Capt. W. M. Hall's Company (G) of the seventh Regiment. He appears to have been discharged due to disability while in Bowling Green, KY. The spelling of the last name on the Capt. could also be Hull. Any info would be appreciated.
