History

The earliest European settlement in the area began after John Harrison negotiated the purchase of land in 1701 from the Lenni Lenape Native Americans who had long occupied the area. In 1783, during the American Revolutionary War, General George Washington camped at Rockingham, the house owned by the Berrien family; he would pass through the area again in 1789 on his way to New York City for his inauguration as President of the United States. Before roads were improved and people traveled by automobiles, it was known as the Devil’s Featherbed because it was difficult to travel the rocky terrain by horse and wagon.

Rocky Hill was incorporated as a borough by an act of the New Jersey Legislature on December 18, 1889, from portions of Montgomery Township, based on the results of a referendum held four days earlier.
