Wolfert Gerritse van Couwenhoven

Wolfert Gerritse Van Couwenhoven (1 May 1579 – 1662), also known as Wolphert Gerretse van Kouwenhoven and Wolphert Gerretse, was an original patentee, director of bouweries (farms), and a founder of the New Netherland colony.
He also founded the first European settlement on Long Island, called New Amersfoort, and was a Schepen of New Amsterdam in 1654. He is noted as playing an "active role in laying the foundations of the communities of Manhattan, Albany, Rensselaer, and Brooklyn."
The progenitor of the Vanderbilt family, Jan Aertszoon (1620–1705), also known as Jan Aertson, a Dutch farmer from the village of De Bilt in Utrecht, Netherlands, emigrated to the Dutch colony of New Netherland as an indentured servant to the Van Kouwenhoven family in 1650.

Career.
Dutch West India Company.
Wolfert ran a baking and clothes bleaching business, when in 1625 he was assigned as one of the first settlers to cultivate farms in the New Netherlands colony by the Dutch West India Company.
Director of Bouweries for Kiliaen van Rensselaer.
In 1630, he returned to the Netherlands, where he entered into a contract with Kiliaen Van Rensselaer to return to the colony to manage his farms. Wolphert arrived back in the colony aboard the ship "Eendracht", where he proceeded in his duties as director for van Rensselaer's farms in Rensselaerwyck and Fort Orange.
His contract was to run through 1636, but Gerretse requested it cancelled early so he could pursue his own interests. Rensselaer agreed. In 1632, Gerretse was released from his contractual obligations.
New Amersfoort.
Shortly thereafter, he leased a bouwerie in New Amsterdam and managed it until 1636, when he was granted a patent of several hundred acres on Long Island. He called his plantation "Achervelt"; later it served as the founding of the town of New Amersfoort, named after Gerritse's original home. Today the area is known as Flatlands. His plantation was located near the current intersection of King's Highway and Flatbush Avenue.
In 2007 the deed of the granted land in Long Island was sold to a private collector for $156,000 becoming "one of the oldest Dutch documents in private hands". The deed dated 6 June 1636 is written in Dutch and outlines the purchase of the land (3,600-acre) from the Lenape Indians.
Public service.
In 1637, he became a Freeholder in Midwout, and again in 1641. In 1653, he was sent by the colony to the States-General in the Netherlands as a Commissioner. In 1654, Wolphert served as a Schepen of New Amsterdam, and in 1657 was made a Burgher. He served on the citizens council of Eight Men.
