The Munsees were the northernmost of an affiliated group of Indian Villages that came to be known as the Lenni Lenape or, Delawares. They were an agricultural, hunting, fishing and gathering people, living in settlements along the tributary streams that flowed into the Delaware River and the Hudson River on their southward journey through the present States of Pennsylvania, Delaware, New York and New Jersey.
The northernmost Lenni Lenape, were known as the Minisink, (People of the Stony Country) and later Munsee. Further south were the Unalami (People up The River), then still further south a large group known as Unami (People down the River), and finally on Delaware Bay were the Unalachtigo (People near The Ocean).
The total population of the Lenni Lenape, at the time of permanent European contact (Henry Hudson in 1609), has been estimated at a low range of approximately 6,000 to 8,000 people, to a high range of 65,000 in their traditional territory.
