Stump Grinding in Rockville Centre

The site of Rockville Centre has been occupied by humans for thousands of years. Generally speaking, the people of the prehistoric Woodlands period East River culture are believed to have been the Algonkian-speaking ancestors of the historical Indian tribes of western Long Island. The historical territory of their Lenape descendants, the Canarsie, Recouwacky (Rockaway), Matinecock and Massapequa, included present-day western Long Island’s Queens and Nassau Counties.

By the year 1643, there were roughly thirteen Algonquin bands (then referred to as tribes) living east of the Dutch-English settlements: the four or so Lenape chieftaincies in western Long Island, and Metoac descendants of the prehistoric Woodlands period Windsor culture living on eastern Long Island, considered by some to be branches of the Pequot: Merrick, Nissequoge, Secatoag, Seatauket, Patchoag, Poosepatuck (also called Uncachogee), Corchaug, Shinnecock, Manhansett (also called Manhasset), and Montaukett.

Imported diseases had decimated the natives in 16th century. While disease was still a major factor during the decades of the 17th century, native mortality in western Long Island due to disease was similar to that of the settlers. Most Lenape were pushed out of their homeland by expanding European colonies; the colonies received many emigrants while the Munsee-speaking Indian communities did not. Their dire situation was exacerbated by losses from intertribal conflicts.
