|Issue||William de Ferrers, 4th Earl of Derby|
|Father||Robert de Ferrers, 2nd Earl of Derby|
William was the son of Robert de Ferrers, 2nd Earl of Derby, and his wife, Margaret Peverel. He succeeded his father as Earl of Derby in 1162. He was married to Sybil, the daughter of William de Braose, 3rd Lord of Bramber, and Bertha of Hereford.
William de Ferrers was one of the Earls who joined the rebellion against King Henry II of England led by Henry's eldest son, Henry the Younger, in the Revolt of 1173–1174, sacking the town of Nottingham. Robert de Ferrers II, his father, had supported Stephen of England and, although Henry II had accepted him at court, he had denied the title of earl of Derby to him and his son. In addition, William had a grudge against Henry because he believed he should have inherited the lands of Peveril Castle through his mother. These, King Henry had previously confiscated in 1155 when William Peverel fell into disfavour.
With the failure of the revolt, de Ferrers was taken prisoner by King Henry, at Northampton on 31 July 1174, along with the King of Scots and the earls of Chester and Lincoln, along with a number of his Derbyshire underlings and was held at Caen. He was deprived of his castles at Tutbury and Duffield and both were put out of commission (and possibly Pilsbury.) In addition to defraying the costs of the war, Henry levied a so-called "Forest Fine" of 200 marks.
He seems to have afterwards regained the confidence of Henry II., and he showed his fidelity to the next Sovereign, (King Richard I.), by accompanying him in his expedition to the Holy Land, and joining the Third Crusade and died at the Siege of Acre in 1190.
He was succeeded by his son William de Ferrers, 4th Earl of Derby.
