Would like some help finding information on my gggrandfather.His name was John f. harrell. He served in co. D/F of the 27th. Would like to know if wounded or captured and the like.I have found some information from rosters.His name is often mispelled on most rosters and rolls.He appears on rosters after the fall of Ft. Donelson so were did he go or was he captured and released later. It's all a mystery to me so far. Thank you in advance for any help. Kent
