Seatuck Creek

Seatuck is a creek or river at Eastport on the boundary between Southampton and Brookhaven. Seatuck appears frequently in early records as the western boundary of Southampton. The related form Seatquaa referred to a neck of land eastward of Hempstead and is treated as a related form. Seatuck and Seatquaa are connected with words for the mouth of a tidal stream or land at a creek mouth.
