Along with other German-surnamed relations of the British royal family, Alexander also changed his surname at that time, to Mountbatten. The titles became extinct upon Lord Carisbrooke's death in 1960, as he had no sons.

Carisbrooke Castle was the residence of Prince Henry and Princess Beatrice as Governor of the Isle of Wight. The title of Marquess of Berkhampstead had previously been conferred with the Dukedom of Cumberland on Prince William Augustus, son of King George II, in 1726. The title of Viscount Launceston had previously been conferred with the Dukedom of Edinburgh on Prince Frederick Louis, later Prince of Wales, also in 1726.
