Mount Sinai, New York, was officially established in 1664, having been known as Old Mans. The name was changed to Mount Sinai in 1840. Over 5,500 years ago, Mount Sinai was home to a large Native American population. They sold the land that is Mount Sinai for goods including coats, stockings, shirts, kettles, knives and hatchets.
Our own Cedar Beach was where a patriot landing party of the American Revolution landed and made its way to Shirley and the Manor of St. George, where they burned British supplies. Early settlers engaged in shipbuilding, farming and fishing.

The Long Island Rail Road's Port Jefferson line ran through Mount Sinai until 1939, bringing families to summer cottages on the beach. Such authors and actors as Mark Swan, Lionel Barrymore, Dawn Powell and Arthur Miller sought or rented homes in Mount Sinai. Marilyn Monroe visited Mount Sinai in the 1950's.
