The Soldiers and Sailors System (http://www.itd.nps.gov/cwss/) indicates a Theodore Kuhn served in Company L of the 4th Kentucky Volunteer Cavalry. The 4th Ky. Cav. was organized in Louisville, KY and had many German-speaking men in it.
I could not find him in the Ky. Report of the Adjutant General for the Civil War in the 4th Ky. Cav. However, some names have been
inadvertantly omitted. The S & S System indicated that he was listed on National Archives Microfilm M386 Roll 15.
I suggest you contact Brandon Slone at the Ky. Dept of Military Affairs and see what he can find for you. E-mail Brandon at
