I am doing research on my extended family, and found one of my distant relatives died at the Battle of Bentonville (NC) @ 3/19-21/1865. John Robert Martin (J R Martin) was a member of the 7th SC Rifles Co. B (Kershaw Brigade). I have not been able to find a list of dead buried in the mass grave at the battle site. Can anyone help with a list of burials, as I am trying to determine if he is buried there?
