Marshall N is in MSG, and lands in Capt. Lowes Artillary (Jackson Battery) enlisted at Cave Creek Arkansas Feb 27th 1862. He was at Lexington and Elkhorn while in MSG.(Martin's Regt.) He ends up captured at Vicksburg. That the last military record I find. He ends up married, lives life in the KC area and serves as Postmaster at Stoney Point MO. see: https://www.fold3.com/image/105604205
I find nothing that says he went to Quantril but certainly was MSG.

Marion was a twin to Marshall.
