Alexander Duff, 1st Duke of Fife  Alexander William George Duff, 1st Duke of Fife, (10 November 1849 – 29 January 1912) styled Viscount Macduff between 1857 and 1879 and known as The Earl Fife between 1879 and 1889, was a Scottish peer who married Princess Louise, the third child and eldest daughter of King Edward VII and Queen Alexandra. Fife was born Alexander Duff in Edinburgh, the son of James Duff and his wife, Lady Agnes Hay. His father was a grandson of the 3rd Earl Fife and heir presumptive to the 4th Earl Fife. His mother was the second daughter of the 18th Earl of Erroll and his wife, Elizabeth FitzClarence, an illegitimate daughter of King William IV. When his father succeeded as 5th Earl Fife in 1857, Duff acquired the courtesy title of Viscount Macduff. He attended Eton from 1863 to 1866. Fife served as Member of Parliament for the Elginshire and Nairnshire constituency, in Scotland, from 1874 to 1879. On 7 August 1879, he succeeded his father as 6th Earl Fife in the Peerage of Ireland (and as 2nd Baron Skene in the Peerage of the United Kingdom, which title gave him a seat in the House of Lords). He served under William Ewart Gladstone as Captain of the Honourable Corps of Gentlemen-at-Arms from 1880 to 1881, and served on a special diplomatic mission to the King of Saxony in 1882. He was also Lord-Lieutenant Elginshire from 1872 to 1902, and Lord Lieutenant of the County of London from February 1900 until his death in 1912. He was appointed Honorary Colonel of the 1st Banffshire Artillery Volunteers on 15 March 1884. In 1885, Queen Victoria created him Earl of Fife in the Peerage of the United Kingdom. He took part in the founding of the Chartered Company of South Africa and served as one of its vice presidents until the Jameson Raid of 1896. On Saturday 27 July 1889, Lord Fife married Princess Louise, the eldest daughter of the then-Prince and Princess of Wales, at the Private Chapel at Buckingham Palace. The couple were third cousins in descent from George III. The wedding marked the second time a descendant of Queen Victoria married a British subject (the first being the marriage of The Princess Louise, the Queen's fourth daughter, to the Duke of Argyll).
