In this detail from a map of Burlington County, Mount Holly is represented as a residential center with connections to the region. The map’s orientation is tilted, so that north is in the upper left corner of the map, not at the top. Immediately left of the town, shading indicates the holly-covered hill that inspired the name Mount Holly. The diagonal line extending across the map is the Burlington and Mount Holly Rail Road linking the two towns. Also nearby, the map documents the presence of the free black settlement Timbuctoo. Founded in 1820, Timbuctoo was a haven for former slaves who escaped to New Jersey using the network of the Underground Railroad.
