THE De GROOT FAMILY, still numerous in Bergen and Hudson Counties, are of Holland descent. William Pietersen de Groot came to America in 1662, on board the ship "Hope," with his wife and five children. They were from Amsterdam, Holland. Dirck Jansen de Groot, a native of Rylevelt, in Holland, came to New Amsterdam as a soldier in the Dutch service, on board the ship "Spotted Cow," April 15, 1660, leaving behind him his wife, Grietie Gerrets, and two children. In April, 1663, Dirck's brother, Staats de Groot, who, the ship's register says, was a resident of Tricht, Holland, came to America on the same ship which had brought over his brother. Staats brought over with him his brother's wife and children. Staats married, in 1664, Barbara Springsteen. Dirck and his first wife, Wybrig Jans, resided in New Amsterdam until 1679, when they removed to Flatbush, L. I., where they remained permanently. From Flatbush several of the children removed to Hackensack in 1695-96. Staats first settled at Brooklyn, where the assessment roll of 1675 showed him to be a taxpayer. He was of a roving disposition. In 1678 he was living in Westchester County, N. Y. He next turned up at Bergen, N. J., where, in June, 1678, his second daughter was baptized. While living at Bergen, where many of his relatives lived, he became in 1686 one of the Tappan patentees. He was at New Amsterdam in 1688, and probably never located on his Tappan lands. He died between 1688 and 1704, having deeded or willed his lands to his wife Barbara, who was a daughter of Casparus Springsteen, of Groningen, Holland. His children were Yoost, Neltje, Mary, and Geesie. Yoost settled at Tappan and his descendants spread into Bergen County. The descendants of Dirck and William Pietersen de Groot spread through Bergen County from Bergen and Hackensack, where they settled.
