Following the death in 1680 of Nathaniel Sylvester, Shelter Island was divided between his two sons, Giles and Nathaniel II. In 1695, William Nicoll, a resident of Islip, bought from Giles the area now called Mashomack Nature Preserve. Three years later, in 1698, another newcomer, George Havens, bought from Nathaniel II. This parcel comprises what today is the Center; it stretched south to South Ferry and west to West Neck Creek. Over time these estates and parcels were split and divided by marriage and purchase, so that by the early 18th century, 20 families lived on Shelter Island. By order of the Provincial Government, the Town of Shelter Island was established in 1730. The community developed from there.
