Brecknock, also known as the Howell's Mill Seat, is a historic home located near Camden, Kent County, Delaware. The house is in four sections; two of brick and two frame. The original one-room house possibly dates before 1700 and is constructed of brick. A brick section was added in the 1740s. The -story, frame, main house was added in the mid-18th century and abuts the second brick section. The final frame section was added in the 1880s and is a four-room apartment originally built for the wagon driver, but later incorporated into the house.
It was added to the National Register of Historic Places in 1974.
