Princess Mary Adelaide of Cambridge Duke and Duchess of Teck chose to reside in London rather than abroad, mainly because Mary Adelaide received £5,000 per annum as a Parliamentary annuity and carried out royal duties. Her mother, the Duchess of Cambridge, also provided her with supplementary income. Requests to Queen Victoria for extra funds were generally refused; however, the queen did provide the Tecks with apartments at Kensington Palace and White Lodge in Richmond Park as a country house. Mary Adelaide requested that her new husband be granted the style "Royal Highness", but this was refused by Queen Victoria. The queen did, however, promote Francis
Prince Adolphus, Duke of Cambridge of Prince Frederick of Hesse. From 1816 to 1837, the Duke of Cambridge served as viceroy of the Kingdom of Hanover on behalf of his elder brothers, George IV and later William IV. When his niece succeeded to the British throne on 20 June 1837 as Queen Victoria, the 122-year union of the crowns the United Kingdom and Hanover ended, due to Hanover being under Salic Law. The Duke of Cumberland became King of Hanover and the Duke of Cambridge returned to Britain. The Duke of Cambridge died on 8 July 1850 at Cambridge House, Piccadilly, London, and was buried
