It was announced from Bucking Palace today that: “The Queen has today been pleased to confer a Dukedom on Prince William of Wales. “His titles will be Duke of Cambridge, Earl of Strathearn and Baron Carrickfergus. Prince William thus becomes His Royal Highness The Duke of Cambridge and Miss Catherine Middleton on marriage will become Her Royal Highness The Duchess of Cambridge.” The titles Cambridge is for England, Strathearn for Scotland, Carrickfergus for Northern Ireland. The last holder of the dukedom of Cambridge was Prince George, a grandson of King George III. George, Duke of Cambridge, also married a commoner, Sarah Fairbrother. Unlike Prince William, whose marriage to Catherine Middleton has the blessing of the queen and government, Prince George’s marriage did not enjoy the imprimatur of the monarch. The dukedom of Cambridge was first granted in the mid-seventeenth century.
