Dame Helen Mirren, recently awarded an Oscar for her potrayal of Queen Elizabeth II, "was born Ilyena Vasilievna [Lydia] Mironov...in Ilford, Essex, [United Kingdom] the second of three children of a father of Russian origin and an English mother. Mirren's paternal grandfather, a Russian nobleman, tsarist colonel and diplomat, was negotiating an arms deal in Britain and was stranded there, along with his family, during the Russian Revolution. Her father, Vasily Petrovich Mironov, called himself Basil and changed the family name to Mirren in the 1950s. He played the viola with the London Philharmonic before World War II and, after it, drove a cab and was a driving-test examiner...Her great-great-great-great-grandfather was field-marshal Mikhail Kamensky, one of the Russian heroes of the Napoleonic wars."
