I'm interested in finding out more about my great-grandfather, J.M. Parmer. He was Cherokee, and served as an Indian scout with the 20th Texas Cavalry during the Civil War. He was born Dec. 12, 1844, and died Sep. 28, 1929. He was from the Lampasas region, but later moved to Miles, Texas, in Runnels County. He was a Methodist circuit preacher later in life. Any additional information or leads would be greatly appreciated.
