Duke of Cumberland
Duke of Cumberland is a peerage title that was conferred upon junior members of the British Royal Family, named after the county of Cumberland.
The earldom of Cumberland had been created in 1525, but became extinct in 1643. The first creation of the dukedom, in the Peerage of England, was in 1644 for Prince Rupert of the Rhine, nephew of King Charles I. When he died without male heirs, the title was created again in the Peerage of England in 1689 for Prince George of Denmark, husband of Princess Anne, younger daughter of King James II. He also died without heirs, in 1708. Neither of these men, however, was usually known by their peerage title.
The third creation, in the Peerage of Great Britain, was for Prince William, the third son of King George II. Other titles granted to Prince William were Marquess of Berkhampstead, Earl of Kennington, Viscount Trematon and Baron Alderney. Since the Prince died unmarried and without children, his titles became extinct at his death.
