And here is the match for Martin W Rider.
So now you've got the 1st and 2nd Lt of Company C 2nd MO Regiment or 12th MO Cav Shelby's Brigade. Note also the obtuse no War Dept Record note and the same surrender info at Lexington.
I think this is starting to look a bit more organized than just a bunch of boys heading back home.
I'm working from the MO div SCV list for 12th cav Co C.
Seems several of these have a common 1864 muster date that did not get paroled at Shreveport, maybe another common thread. I'll build a list and cross it back to Todd and Quantrill's list.
