Stock Photo - Princess Irina Youssoupoff, niece of Tsar Nicholas II and wife of Felix Youssoupoff who is pictured in a fancy dress costume. Prince Felix Youssoupoff came from a wealthy, aristocratic Russian family (1886-1967) and was a distant relative of the Tsar. In 1916, along with four other Russian aristocrats, he was responsible for the murder of Grigori Rasputin, the holy monk who exerted heavy influence on the Imperial couple, particularly the Tsaritsa, Alexandra who believe Rasputin could cure her haemophiliac son, Alexei. Youssopoff's memoirs report on the murder of Rasputin vividly and perhaps exaggeratedly. The Youssopoffs were part of a group of survivors of the imperial family who escaped the Bolsheviks on the HMS Marlborough in 1919.
