My ancestors obit states that he served with Co. A 23rd Texas Cav. HIs name was James William Plunkett and he lived in Sulphur Springs, Hopkins County, Texas. He was born on 09-16-1829 in Gwinett County, GA. and died 06-14-1914 in Hopkins county. I show that he enlisted in 1862. I would like to hear from anyone who can help me confirm this info, and also would like to know more about the unit and specific battles and theater of operations.
