Pvt. John Hardgrave was a 44-year-old farmer when he enlisted on January 10, 1864, in Company D. He was born in Williamson County. It is believed that Pvt. Hardgrave was enslaved by the white family of Francis Hardgrave who lived in Davidson County, near the Williamson County border. In 1827, Francis Hardgrave left his grandson Francis Hardgrave a "negro boy named John." In the 1830s, members of the Hardgrave family - including many who live in Williamson County - moved to Johnson County, Arkansas, and it is believed they brought John Hardgrave with them.
