Thanks for your reply.
John G. Deatherage was a Pvt. with the 8th VA cavalry but, it's a bit unclear which comapany; his haedstone at the Confederate cemetery, Camp Chase, shows him in Company D but, my Gr. grandfather and a cousin, Franklin, are shown in Company B. Various enlilistment records and muster rolls show John in comapny B, D, or F. My guess is the family stayed together and he was probably in company B.
The other two Deatherages in the 50th were cousins of my Gr. Grandfather :
Emery Dent Deatherage, Sgt., Co. K was captured at the Wilderness, May, 1864 - He survived the war, moved to Missouri and eventually to Texas. He is buried at the Confederate Cemetery in San Antonio.
Lehbon Hillary Deatherage,Pvt., Co. K, was also captured at the Wildrness and survived the War. He moved to Missouri after the War and stayed there; I can't find the cite now but, I believe he is buried in Henry County, Mo.
Emery & Lehbon were sons of Mathew Gale Deatherage, my Gr Grand father's uncle.
