I don't know if it is possible at this time or not, but I was looking over all the regiments you guys have put in so far, and realized a possibly cool addition?
My family fought for the South during the war, and I have LOTS of stories and actual items from the war that my great uncle saved from his family who passed it to him. I know for a fact my ancestor Samuel Read was part of the 4th Virginia Volunteer Cavalry Regiment. The company he was in was known as the "Black Horse Troop" from Fauquier County Virginia. The regiment fought in many of the famous battles of the war, including Antietam. I will link the wiki page for it, but regardless of if you guys implement it or not, just thought it would be cool to share a little bit of my families history and ties to the war!
