I know this message is quite a few years old; but i hope this gets through.
Where did you find this information on 2nd Lieutenant Edward Plummer Martin{Co.E. 10 Tenn. Cav} & Captain & Captain Jack Hinson?
Also, you state "their company were captured on the Tennessee & Duck river near Waverly, Tennessee" and paroled in May 1865. Do you know when this company was captured? My ancestors' cousin (10th Tenn. Cav. Co. "I") was captured at Waverly,possibly at the same time. His younger brother was in the same regiment, same company as Martin;Co. "E". But captured in July '63.
Best Regards
