1671 Census of the Delaware

"The first permanent settlement of the South River began in 1638 with the founding of New Sweden at Fort Christina (now Wilmington), a colony that spread northward to the Schuylkill and southward to Sand Hook (New Castle) by 1655. In that year, New Sweden surrendered to New Netherland and remained under Dutch rule until 1664, when the Dutch surrendered the river to the forces of the Duke of York. Thereafter, up to the time of the first English census in 1671, it remained a part of the Colony of New York, governed out of Fort James on Manhattan Island."--Pref.
