In addition,
From the same source, I deduced this Captain Hamilton was: probably Capt. and Quartermaster Eli Janney Hamilton of the 39th VA Cav.
By the way, I see there was "also" a Pvt Samuel F.White who was paroled at Winchester on 4-30-1865.
Let me know if you would like further info on this Pvt Samuel F.White.
