Thomas Frank Hallmark was the brother of George W. Hallmark, James Washington Hallmark, and John Madison Hallmark.
Although they were all born in Fayette County, Ala, they were living in Marion County at the time the war broke out.
George, James, and Thomas joined up with the First together in 1862. The fourth brother, the youngest, John, was only about 15 when the war started. He joined the unit in 1863. He was the only one who survived the war and made it back home.
There was also a 5th Hallmark brother who refused to join up with either side and hid out in the north Alabama woods for most of the war. The local home guard beat their father to death and shot and killed one of their sisters because of the brothers' decision to fight for the Union instead of the CSA.
