James George Alexander Bannerman Carnegie, 3rd Duke of Fife (23 September 1929 – 22 June 2015) was a British landowner, farmer and peer.

[2] 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 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] As a young man, the Duke's name was variously linked with Princess Margaret, ballerina Mary Drage, and sportswoman Divina Galica.
