I think this is your man. Ellington Mo. was called Barnesville during the civil War. Before that it was called Logan Creek.
Looks like most of his witnesses were in Clardy's
I have no info on Pollock's Regiment
Not sure about Chronister's service before Clardy's. Needs more research there.
Yes, when they surrendered they were there in the flesh. It's in the O. R.. The Federals provided rations for them while they were there, etc
I will check with some friends in Ellington about the wives and post on that later.
