Stop 4: History
History of Sussex County
The area of Sussex County and its surrounding region was occupied for approximately 8,000–13,000 years by succeeding cultures of indigenous peoples. The Munsee Indians inhabited the region at the time of European encounter. The Munsee were a loosely organized division of the Lenape (or Lenni Lenape), a Native American people also called "Delaware Indians" after their historic territory along the Delaware River. The Lenape inhabited the Mid-Atlantic coastal areas and inland along the Hudson and Delaware rivers. The Munsee spoke a very distinct dialect of the Lenape and inhabited a region bounded by the Hudson River, the headwaters of the Delaware River and the Susquehanna River, and south to the Lehigh River and Conewago Creek.
