Suffern is a village that was incorporated in 1796 in the town of Ramapo in Rockland County, New York. Suffern is located 31 miles northwest of Manhattan. As of the 2010 census, Suffern’s population was 10,723.

“The Point of the Mountains” or “Sidman’s Clove” were names used back the American Revolution to apportion the gift village of Suffern. The area originally was inhabited by the Ramapough, a tribe of Munsee, who were a isolation of the Lenape tribe. Upon Sidman’s death, this estate passed into the hands of his son-in-law, John Smith, who sold it to John Suffern.

The village of Suffern was founded in 1796. John Suffern, first Rockland County judge, 1798–1806, settled close the base of the Ramapo Mountains in 1773, and called the place New Antrim, after his house in County Antrim, Northern Ireland. His French Huguenot ancestors had contracted there after fleeing religious persecution in France. New Antrim’s location was considered expediently important in the Revolutionary War because it was at an important crossroads near Ramapo Pass. General George Washington and new important military leaders used John Suffern’s home as headquarters once they were in the area.

This history has been credited by the town.
