Inscription
Jacob Airgood has no gravestone with his name on it. His exact burial location at Stones River Nat'l Cemetery is unknown. Jacob Airgood's "Complete File" papers dated 1863 from the National Archives say his burial locality and grave is "1221." However, Jacob Airgood is not buried at Stones River National Cemetery at the stone marked "1221" because the cemetery's numbering system is different; it is the order of burial for the soldiers after the cemetery was created in 1865 by Abraham Lincoln. Jacob Airgood was not the 1221st person buried at the cemetery but he is certainly in the oldest section of the cemetery. His body was likely moved to the new cemetery from somewhere nearby. Unidentified burials are mixed in with the known burials; they are not in one separate location.
His name appears on the Stones River National Cemetery website, top of page 5, but with no grave number.

The National Park Service was very helpful with explaining how the burials were placed in 1865 after so many soldiers had already died before the creation of the cemetery.
