Are you looking for a specific unit? I had two relatives in the First Battalion Virginia Reserves who were attached to Barton's Brigade on several occassions from late 1864 through the end of the war. I'm currently reading two books that discuss The Appomattox Capmaing: "The Appomattox Campaign" by Chris Calkins and "To Appomattox Nine April Days, 1865". I'd be interested in any other info you may have on this brigade.
