History
Pre-incorporation (pre-colonization – 1910)
The location of what is now the Village of Plandome was originally inhabited by Matinecock Native Americans. These Native American inhabitants called the area Sint Sink, meaning "place of small stones."
During the 17th century, Dutch and English colonists began to settle the area, with fishing in Manhasset Bay and farming serving as a major industries. In 1623, Cow Neck was claimed by the Dutch West India Company, and they began forcing English settlers to leave in 1640. A land purchase in 1643 made it possible for English settlers to return to Cow Neck. This era saw members of prominent colonial families settle on the peninsula, including members of the Mitchill, Nicolls, and Willets families. The Mitchill family, which settled in the area in 1694, owned a significant portion of the land which would eventually become the village – as did the George Willets, of the Willets family, which has long had a large presence on Cow Neck and across Long Island.
