Blackbird Hundred

Blackbird Hundred is an unincorporated subdivision of New Castle County, Delaware.

Hundreds were once used as a basis for representation in the Delaware General Assembly, and while their names still appear on all real estate transactions, they now have no purpose except as a geographical point of reference.

Blackbird Hundred is that portion of New Castle County that lies south of Blackbird Creek and Cypress Creek, a tributary of the Chester River.

It was formed from Appoquinimink Hundred in 1875 and was named for Blackbird Creek that flows along its northern boundary.

Important geographical features, in addition to Blackbird Creek, include the Delaware River, which forms its eastern boundary, the Smyrna River, formerly known as Duck Creek, which forms its southern boundary, and the North West Branch of the Smyrna River.
