Overview
Princess Catherine Ivanovna of Russia (; 12 July 1915 (O.S.) – 13 March 2007) was a great-great-granddaughter of Tsar Nicholas I of Russia and a niece of King Alexander I of Yugoslavia. She was the last member of the Imperial Family to be born before the fall of the dynasty. She was also second cousin of Prince Philip, Duke of Edinburgh, as Catherine's grandfather Grand Duke Konstantin Konstantinovich of Russia was younger brother of Prince Philip's grandmother Olga, Queen of Greece. Her relation to Prince Philip makes her a second cousin, once removed of King Charles III of the United Kingdom. She is also the grandmother of actor Sebastian Arcelus.
Life
Born in Pavlovsk Palace, she was the second child of Prince John Konstantinovich of Russia and Princess Helen of Serbia. After the Revolution, her father was arrested and deported from the capital and her mother followed her husband into exile. Catherine and her brother, Vsevolod, remained in the care of her grandmother, the Grand Duchess Elizaveta Mavriekievna of Russia. On 18 July 1918, their father, Prince John, was killed, and their mother, Princess Jelena, was arrested and spent several months in Soviet prisons. Grand Duchess Elizabeth was able to take Catherine and her brother to Sweden. Sometime later, they were reunited with their mother.
The family lived in Yugoslavia, then moved to England. There, Catherine received an excellent education, although she never learned the Russian language because her mother, devastated by her husband's death, did not want her children speaking that language in front of her.
Marriage
From 1937 to 1945, Princess Catherine Ivanovna lived in Italy, with her great-aunt Queen Elena. During her stay she married an Italian diplomat Ruggero Farace, Marchese di Villaforesta (4 August 1909 - 14 September 1970), in Rome on 15 September 1937; on occasion of her wedding, she renounced to her succession rights to the Russian throne.
