Grand Duchess Olga Nikolaevna of Russia was the eldest daughter of Tsar Nicholas II, the last autocratic ruler of the Russian Empire, and of Empress Alexandra of Russia. During her lifetime, Olga's future marriage was a matter of great speculation within Russia. Matches were rumored with Grand Duke Dmitri Pavlovich of Russia, Crown Prince Carol of Romania, Prince Edward, eldest son of Britain's George V, and with Crown Prince Alexander of Serbia. Olga herself wanted to marry a Russian and remain in her home country. During World War I, Olga nursed wounded soldiers in a military hospital until her own nerves gave out and, thereafter, oversaw administrative duties at the hospital. Olga's murder following the Russian Revolution of 1917 resulted in her canonization as a passion bearer by the Russian Orthodox Church. She was an elder sister of the famous Grand Duchess Anastasia Nikolaevna of Russia, who was widely rumored to have survived the assassination of the Imperial Family. In later years, when dozens of people made claims to be surviving members of the imperial family, a woman named Marga Boodts claimed to be Grand Duchess Olga. Few people took Boodts' claim seriously.
