Native American land deeds recorded by the Dutch from 1636 state that the Indians referred to Long Island as Sewanhaka. Sewanhacky and Sewanhacking were other spellings in the transliteration of the Lenape. Sewan was one of the terms for wampum, commemorative stringed shell beads, for a while also used as currency by colonists in trades with the Lenape, and is also translated as "loose" or "scattered", which may refer either to the wampum or to Long Island. The name "'t Lange Eylandt alias Matouwacs" appears in Dutch maps from the 1650s, with 't Lange Eylandt translating it to "Long Island" from Old Dutch. The English referred to Long Island as "Nassau Island", after the House of Nassau of the Dutch Prince William of Nassau, Prince of Orange (who later also ruled as King William III of England). It is unclear when the name "Nassau Island" was discontinued. Another indigenous name from colonial time, Paumanok, comes from the Native American name for Long Island and means "the island that pays tribute."
