While searching the McNairy Co. GenWeb I followed links that took me to 6th Cav., Union Army.In Company B I found Abraham Sipes, Pvt., age 52, enlisted August 25, 1862, mustered Nov. 13, 1862 and discharged Apr. 13, 1865.Also in Company B was John Sipes, age 19, Corp., enlisted on the same date as Abraham and mustered in the same date.John died Apr. 4, 1864.I would guess this John was Abraham's son.
Also in the 6th Cav., Union Army, in Company G was my great grandfather, John A. Sipes.He enlisted Jan. 9, 1864, age 18 (I believe he was actually 16 since he was only 2 on the 1850 census).He was mustered Mar. 9, 1864.
