I have a Benjamin F. Carpenter, Cpl to Sgt Company K, 6th Texas Cavalry Regiment. Company K came out of the Indian Territories in Sept 1861 and enrolled in mass with the 6th Texas Cavalry as Company K. The Company Commander was Throckmorton, a future Governor of Texas. The compsny had origanily mustered in Mckenny, Collin County. This Carpenter lived through the war and was paroled in 1865. At one point he was listed as a mechanic in Phifer's Brigade. That would be from June 1862 to October 1862. After that the 6th became a part of Whitfield's Texas Cavalry Brigade. There are 17 records on footnote and he was 24 years old. IS THIS YOUR MAN.
