All titles are in the Peerage of England, save for the Barony of Howard of Glossop which is in the Peerage of the United Kingdom. All descend to heirs male except the Barony of Beaumont, which can pass in the female line. The style "Earl of Arundel" is used as a courtesy title by the Duke's eldest son, the present one of which is Henry Fitzalan-Howard, Earl of Arundel. The style "Lord Maltravers" is used as a courtesy title by the eldest son of the Duke's eldest son (the Duke's grandson).
