to allow this to be passed to his heir - his granddaughter (the Dukedom could not be inherited). Marquess, then Duke of Kent Henry Grey (1671–1740) succeeded his father, Anthony Grey, as the 12th Earl of Kent in 1702. In 1706, he was elevated to Marquess of Kent, along with Earl of Harold and Viscount Goderich. In 1710 he was elevated once again as Duke of Kent, and following the death of his sons, Marquess Grey (1740) with a special remainder to his granddaughter. Henry had one son and five daughters with his first wife, Jemima Crew (d. 1728), and one son and one daughter with his second wife, Sophia Bentinck (d. 1741). By the time of Henry's death in 1740, both of his sons had died, Anthony (in 1723) and George (in 1733), leaving the Duke of Kent without a male heir. His granddaughter Lady Jemima Campbell would inherit two titles in her own right, Marchioness Grey and Baroness Lucas; but all Henry's other titles, particularly Duke of Kent, became extinct with his death. Royal dukedom, 1799 On 23 April 1799 the double dukedom of Kent and Strathearn was given, with the earldom of Dublin, to King George III's fourth son, Prince Edward Augustus. Edward had only one legitimate child, a daughter, Princess Alexandrina Victoria (the future Queen Victoria). Upon Edward's death in 1820, the dukedom of Kent and Strathearn became extinct, as he had no legitimate male heir. Royal earldom, 1866 The next creation of a title of Kent was not that of Duke or Marquess, but rather that of Earl, with the creation of Prince Alfred (1844–1900), the second son of Queen Victoria and Prince Albert, as Duke of Edinburgh, Earl of Ulster, and of Kent in 1866. The Duke of Edinburgh (who later became the reigning Duke of Saxe-Coburg-Gotha) had only one son, Prince Alfred, who would have inherited his father's titles had he not died before his father in 1899. With Prince Alfred's death in 1900, the earldom became extinct. Royal dukedom, 1934 In 1934, Prince George (1902–1942), the fourth son of King George V of the United Kingdom and Queen Mary, was created Duke of Kent, Earl of St Andrews and Baron Downpatrick. Prince George had three children before his death in 1942: Prince Edward, Princess Alexandra, and Prince Michael. Prince Edward, upon his father's death, succeeded to his father's peerages.
