Born in France, he took British citizenship in 1938 and lived with his grand mother Grand Duchess Xenia Alexandrovna in England until her death in 1960. The following year, Prince Alexander Nikitich became the first member of the Romanov family to visit Russia after the Revolution.
At the outbreak of the Second World War Prince Alexander and his family were in France and unable to return to the United Kingdom so he was taken to Rome first and then on to Czechoslovakia which resulted in the family almost being repatriated to Russia.[2] Following the conclusion of the war he returned to Britain before moving onto the United States to study at Columbia University. He returned to Britain in 1953 and stayed with his grandmother Grand Duchess Xenia at Hampton Court.[2] He helped to raise funds for a new Orthodox church, after the old temple near Buckingham Palace was destroyed. After the death of his grandmother in 1960, Alexander Nikitich moved to New York, where he worked as translator for a publishing house, worked in advertising, as well as doing historical and genealogical research.
On 27 May 1961 he became the first descendant of the Imperial Family to return to Russia after its members went into exile or were murdered by the Communists following the October Revolution, when he managed to get a visa to join a group of tourists. During his stay he visited Moscow, St Petersburg (although at the time the city was called Leningrad) the former capital of the Russian Empire and the estate of the Princes Yusupov in Arkhangelskoye, near Moscow.[2][3]
Prince Alexander married a Sicilian princess, Maria 'Mimi' Valguarnera (29 November 1931, Palermo, Italy - 29 September 2023, New York City), daughter of Corrado, Prince of Niscemi and Castelnuovo and Duke of Arenella, on 23 February 1971 in New York City in a civil ceremony, and in a religious ceremony on 18 July 1971 in Cannes.[1][4] His wife converted to Orthodox Christianity before their marriage. The couple lived in New York City and in London. They had no children.
In 1979 Prince Alexander Nikitich became a member of the Romanov family association. In 1992 he participated in the meeting of the seven princes of the Romanov family in Paris.
Prince Alexander Nikitich Romanov died after a brief illness, 21 September 2002 in London. His body was cremated at Mortlake Crematorium and buried in the ancestral tomb of his wife's family in Palermo.
