Thank you George. It is the same man. The record of "J.A." Gardner also lists him as A.J. Gardner. Co. E was formerly Co. B. Napier's Battalion, mostly from Clarksville in Montgomery County. Andrew Jackson Gardner was from a farm between Ft. Henry and Dover, neighboring Stewart County---behind enemy lines by March 1862. He had no where else to go. My cousins made extensive research on the local 1860 census surveys. There was no other A.J. Gardner in either county and no J.A. Gardner.

But, you gave me some crucial information. A.J. Gardner died in 1890. Since the unit muster rolls expire after May-June 1863, he may have remained in the 10 TN Cavalry for the remainder of the War. Thank you.
