Using free tools from Google Maps, we have launched a dynamic new map of Pennysylvania’s hallowed grounds that attempts to chart the burial locations of black soldiers from Pennsylvania who fought in the Civil War. In particular, this map-in-progress highlights cemeteries that hold the remains of the 100 Voices, or representative figures being memorialized by the 2010 PA Grand Review initiative. For example, three members of the 100 Voices are buried at Midland Cemetery in Steelton, Pennsylvania —Lemuel Butler, Andrew Hill and Charles Henderson. Visitors to the dynamic online map will find photographs and exact GPS coordinates of their headstones (courtesy of Calobe Jackson, Jr.) as well as background information on these men. Each online cemetery marker also includes information such as photographs or videos (where available) of the cemetery and whatever additional background information might be contained within Dickinson College’s House Divided research engine or at the Pennsylvania Grand Review website. This particular Hallowed Grounds map is ongoing project that needs your help. Please feel free to contribute photos, videos, GPS coordinates (obtainable through smart phones or GPU handsets) by sending them to us at email@example.com. Other Civil War Era-related dynamic maps, such as one concerning the Underground Railroad in Pennsylvania or Frederick Douglass’s childhood in Baltimore, have been posted here.
