Here are a couple things to consider before I can look at my research material tonight:
1. The Confederacy did not begin conscription until around April 1862.
2. If you have access to the two volume set "Tennesseans in the Civil War" today, one of the volumes has the names of soldiers both Federal and Confederate that served from Tennessee.
3. Please let us know your source material for your "documentation" of the locations of your ancestors. We consider some sources more reliable than others. I have found that if a Federal soldier died of some unknown reason or that he died in as a POW, the family often times assumes without cause that they died in Andersonville. The most reliable route to go in verification is to first check "Tennesseans in the Civil War" and then to cross reference the regimental history and see if any of the companies of the regiment came from that county then look at the soldier's Compiled Military Service Record and see what it says. For the Federal soldiers you will have to order this from the National Archives in Washington, D.C. For Confederate service, the Tennessee State Library and Archives, the Chattanooga Public Library, and the Eastern Tennessee Historical Society has it on microfilm.
I will check my copy of "Tennesseans in the Civil War" tonight for you.
