William Lamb, 2nd Viscount Melbourne, PC, PC (Ire), FRS (15 March 1779 – 24 November 1848), in some sources called Henry William Lamb, was a British Whig politician who served as Home Secretary (1830–1834) and Prime Minister (1834 and 1835–1841).
William IV (William Henry; 21 August 1765 – 20 June 1837) was King of the United Kingdom of Great Britain and Ireland and King of Hanover from 26 June 1830 until his death in 1837. The third son of George III , William succeeded his elder brother George IV , becoming the last king and penultimate monarch of Britain's House of Hanover .
He intended to marry Lady Caroline Ponsonby, his cousin, but she married William Lamb, which he found devastating. Devonshire died at Hardwick Hall, Derbyshire, in January 1858, aged 67, and left an estate valued at £500,000 in his will. As he was unmarried the dukedom passed to his cousin William Cavendish, 2nd Earl of Burlington.
