I just found an "A.O. LEE, d. Apr. 1, 1862, 25th Inf. Co. D" posted in "Military Annals of Tennessee Confederates", by John Berrien Lindsay, (Pub. 1866)...and I'm thinking this could be the same man I am searching. I guess it's possible there could be two "Lees", one A. and another, A.O. in same Unit. Anyone with more information?
