Re: T.I. Moore, 13th TN Infantry
Top, no Tennessee regiments served in Arkansas. In 19th century cursive, the letters "I" and "J" are often indistinguishable, so you might want to check for soldiers named T. J. Moore, Thomas J. Moore, etc. Also, many soldiers went by their middle names, so check for Irwin (and permutations, such as Erwin) Moore.
