Ve, The Soldiers and Sailors System website http://www.itd.nps.gov/cwss/soldiers.htm for the Civil War has several possibilities. I don't know which ones might have been units from the DeKalb area but there is a book called Tennesseans in the Civil War in the Tennessee State Library and many other public libraries that will tell you. The web site itself will help if you have lots of patience doing unit lookups. Then pull the individual Military Service Cards at the TSLA. Good luck! Anna Bertram abertram@heartoftn.net
