Princess Olga is the youngest child of Prince Andrei Alexandrovich of Russia and the only one born of his second marriage in 1942, to Nadine Sylvia Ada McDougall, daughter of Lt. Col. Herbert McDougall. Her father was the son of Grand Duke Alexander Mikhailovich of Russia, who belonged to a cadet branch of the Romanovs, and his wife Grand Duchess Xenia Alexandrovna, Tsar Nicholas II's sister. Olga Andreevna uses the English version of her family name, preferring 'Romanoff' to 'Romanova', the feminine form of her name in Russian. She is known by the title "Princess Olga Andreevna Romanoff". Educated in her mother's stately home in England by private tutors, she was told of her family's tragic imperial heritage in pre-revolutionary Russia as a child by her exiled father. She joined the Romanov Family Association in 1980 and, with other members, attended the long-delayed interment of Russia's last emperor and empress in St. Petersburg in 1998. On 3 December 2017, nearly a year after the death of Prince Dimitri Romanovich Romanovon the last day of 2016, she was elected president of the RFA. In the interim, the senior male Romanov descendant by primogeniture, Prince Andrew Andreyevich Romanov, was chosen Honorary RFA president. Olga intended to return for the centenary memorial in 2018, at which however, Paul Kulikovsky, a great-grandson of Grand Duchess Olga Alexandrovna, and a contingent of other Romanov descendants represented the RFA. She lives at Provender House in the hamlet of Provender, near Faversham in Kent, where she has restored the 13th century mansion and opened it to tourists. Having inherited the ageing mansion and estate in 2000, she raised the money to have it refurbished by selling what was left of her father's cache of pre-revolutionary artefacts, most of which had long since been sold to the British royal family. In 2005, she was on Australian Princess giving advice to competitors. During an interview on Channel 4 television's "Royal House of Windsor", she revealed that, contrary to the prevalent assumption, the fatal abandonment by the British of Tsar Nicholas II, his wife and children to the Bolsheviks during the Russian revolution was not due to the callousness of the British government of the day, but to the reluctance of his diffident cousin King George V. In 2017 she published a memoir, Princess Olga, A Wild and Barefoot Romanov. She serves alongside Princess Katarina of Yugoslavia as a royal patron of the Queen Charlotte's Ball.
