Part of Dyer's work is on line http://www.civilwararchive.com/regim.htm but the part I mentioned is a list of men Dyer found who belonged to certain regiments. It is not on line to my knowledge. Tennesseans in the Civil War, however, lists Anderson Ray (Co H), James Ray (Co F), James M (Companies E and M), John (Co B), John F (Co E), John R 2nd Lt, John S (Co L), Joseph C (Co L), Moses (Co H), Robert S (Co H), and Samuel B Corp (Co A) all as being in the 6th TN Cav.
