In 1651 Goodyear sold the island to a group of Barbados sugar merchants for 1,600 pounds of sugar. Nathaniel Sylvester (1610–1680), one of the merchants, was the island’s first white settler. He was among a number of English merchants who had lived and worked in Rotterdam (where he was born) before going to Barbados. His connections there and with the Netherlands helped him establish a far-flung trading enterprise. On March 23, 1652, he made the purchase official by agreement with Youghco (called Poggatticut), the sachem of the Manhanset tribe. The other owners, Sylvester’s brother Constant, and Thomas Middleton, never came to Long Island. In 1673 Nathaniel Sylvester claimed ownership of Shelter Island, Fishers Island, and other parts of Long Island. By that time the Manhansett had declined in number and power.
