Duffield Castle, Derbyshire
Henry de Ferrers (Ferrars) faithfully served King William and was given land in Derbyshire, which became known as Duffield Frith. It was between Heage and Shottle on the North, and Tutbury on the South. He built Tutbury Castle as his main residence. He built another castle at Duffield to protect north side of his land. This castle was probably built of wood.
