The Dukedom of Fife was first granted in 1889 to the Duke's grandfather, the 6th Earl of Fife, by Queen Victoria on his marriage to Princess Louise of Wales, the eldest daughter of the Prince of Wales. In April 1900, the first Duke received a new patent as Duke of Fife and Earl of Macduff in the Peerage of the United Kingdom, this time with a special remainder to his daughters by Princess Louise and their male issue. As the only surviving children of the Duke and Princess Louise were two daughters, the dukedom passed to Princess Alexandra, who became Princess Arthur of Connaught.
In the 1990s, Fife's mitochondrial DNA (mDNA) was used to help identify bones recovered in Siberia in 1979 as the remains of Tsar Nicholas II of Russia, who was killed in 1918 by the Communists along with his wife and children. Queen Alexandra, the Duke of Fife's maternal great-grandmother, was the older sister of Nicholas II's mother, Dagmar. The test required a female line descendant, as mDNA is passed unchanged from mother to child, unless there is a mutation. In Fife's case, mDNA from Queen Alexandra passed to his grandmother, Louise, Princess Royal, and then to his mother, Princess Maud, and then to him. Fife's mDNA was a 98.5% match with the bones, a rare imperfect match that scientists suspected was caused by a genetic mutation on the Russian side called a heteroplasmy. In 1994, the remains of Nicholas's younger brother, Grand Duke Georgy Alexandrovich, were exhumed in Saint Petersburg. The mDNA from Grand Duke Georgy also revealed the heteroplasmy, confirming the theory of the mutation and conclusive proof that the bones indeed belonged to the last tsar of Russia.[3]
The marriage produced three children before they divorced in 1966:[1]
