Civil War Cemeteries
The National Park Service manages 14 National Cemeteries, all but one of which is related to a Civil War battlefield park. The NPS is planning on listing all names of burials in these cemeteries on the Civil War Soldiers and Sailors System. The first phase involves data taken from written records of Poplar Grove National Cemetery at Petersburg National Battlefield, and also includes images of the headstones.
