Russian prince
Prince Rostislav Alexandrovich was the sixth child and fifth son of HIH the Grand Duke Alexander Mikhailovich ‘Sandro’ (1866–1933) and HIH the Grand Duchess Xenia Alexandrovna (1875–1960). His parents were paternal first cousins once removed. Consequently, Prince Rostislav was the great-grandson of Tsar Nicholas I (from his father's side), also the great-great-grandson of the same Tsar Nicholas I (from his mother's one), the grandson of Tsar Alexander III and the nephew of Tsar Nicholas II. Prince Rostislav was the favorite cousin of Alexei Nikolaevich, Tsarevich of Russia.
During the Russian Revolution Prince Rostislav was imprisoned along with his parents and grandmother the Dowager Empress at Dulber, in the Crimea. He escaped the fate of a number of his Romanov cousins who were murdered by the Bolsheviks when he was freed by German troops in 1918. He left Russia in 1919 aboard the Royal Navy ship for Malta, where they spent nine months before moving to England and later settling in Cannes, France.
Family
Rostislav was married three times. He married first Princess Alexandra Pavlovna Galitzine (7 May 1905 – 5 December 2006) on 1 September 1928 in Chicago. They had one child before divorcing in 1944. She remarried to Lester Armour.
