    The original settlers of the Town of Brookhaven, based in the neighboring hamlet of Setauket, bought a tract of land from the Setalcott Indians in 1655. The deed included the area of contemporary Port Jefferson along with all other lands along the North Shore from the Nissequogue River eastward to Mount Misery Point.

    Port Jefferson’s original name was Sowaysset, a Native American term for either “place of small pines” or “where water opens.

    The first known home within the present village boundaries was erected in the early 1660s by Captain John Scott, an important leader in Long Island’s early history. This house, named Egerton, was a grand abode on the western end of Mount Sinai Harbor at Mount Misery Neck. The first settler in Port Jefferson’s current downtown was an Irish Protestant shoemaker from Queens named John Roe, who built his still-standing home in 1682. It remained a small community of five homes through the 18th century, and was renamed to “Drowned Meadow” in 1682.
