The southern boundary of Munsee territory was the area north of the Delaware Water Gap, following the river system southeast along the Raritan River to the Atlantic Ocean. To the south of the Munsee were the Unami Delaware. To the north were the Algonquian Mahican, and to the east were the Eastern Long Island peoples, who also spoke Algonquian languages, such as Unquachog (also spelled Unkechaug) and southern New England languages, such as Quiripi. (Quiripi and Unquachog are likely members of a dialect continuum of a single language.)
