Gerrit Hendricksen (1620-1683/1684), probably a son of Hendrick Gerryts and his wife Geertje or Grietje, immigrated in 1637 from Holland to New Amsterdam, New York, and went up river to Rensselaerwick as an employee. By 1646 he was back in New Amsterdam, where he married twice, and was known as Gerrit Hendricksen de blau boer (probably referring to his farm land). His children and later descendants used Blauvelt as a surname. Descendants and relatives lived in New York, New Jersey, Pennsylvania, Ohio, Michigan, Kansas, Iowa, Nebraska, Oregon, Virginia, Delaware, Florida and elsewhere.
