I haven't pinned down this unit's Civil War ancestry yet, but from what I saw in a recent newspaper picture they seemed to be wearing blue, which I assume is Union.   

Kim & Sorcha - I'd forgotten "...Yellow Ribbon" and "Captain Jinks," and I'll have to look up "Jine the Cavalry," - thanks. Will also look up "When Sherman Marched....," although "Marching Through Georgia" is the same story, and I've done it before.
