New Castle County Delaware was home to three signers of the Declaration of Independence, George Read, Thomas McKean, and Caesar Rodney and is the first county of the first state. The Federal-style Read House, built in 1801, was home of the son of a signer of the Declaration of Independence. The first permanent settlement on Delaware soil was Fort Christina currently where Wilmington is. The Swedes first settle in 1640, then followed by the Dutch in 1651. New Castle County borders Pennsylvania to the north, Maryland to the west, the Delaware River to the east.
