Jacob Alrichs, appointed by the City of Amsterdam and the DWIC to become the director of New Amstel, on the South River, arrived on the Prince Maurice in 1657.    It was a very difficult journey, as the Prince Maurice was separated from the other ships in this journey by a storm, and eventually wrecked on the coast of Long Island on March 8, 1657 in the bitter cold.   There were more than 120 settlers on board, and Jacob wrote to Petrus Styuvesant on March 12, requesting immediate assistance for those settlers who had already arrived in Manhattan, and that he send a ship to collect his group as soon as possible.

Jacob says that they are stranded at "Sicktawach," which could be either the Carmans River or the Connetguot River in Suffolk County, Long Island, which would place the shipwreck on Fire Island across the Great South Bay.

Jacob travelled to the New Amstel settlement with his wife.   They did not have children.
