Cors St. Vroom Coursen (1612-1655) was born in 1612 in Langeraer, Netherlands; a
small hamlet about six miles east of Leyden on the Aar River. He migrated to the colonial
province of New Netherlands in 1633 and worked as the skipper of a small vessel carrying
freight between Manhattan and Albany. On his trips down the Hudson River he picked up the
language of the Indians along the way. He then served as an interpreter for the Dutch. He was
an aggressive and undiplomatic person. He once took a parcel of skins from an Indian and then
pushed him overboard. Indians later slapped Cors in the face with a dead squirrel and nearly
caused a war between the Dutch and the Indians. Tryntje Hendricks (1612-1690) was born in
Holland, Reusel-de Mierden, Noord-Braband, Netherlands in 1612. Cors and Tryntje had three
boys: Cornelis (1645-), Peter St. Vroom (1651-), and Hendricks (1653-1693). Cors Coursen
died in 1655. In 1657 Tryntje petitioned for the guardianship of her three boys. She later
married Frederick Lubbertsen. She died in Kings, New York in 1690.
