10. Anna Anderson
After the Communist Revolution in Russia, the royal family, the Romanovs, were killed by the Bolsheviks. But the enduring mystery was whether daughter Anastasia managed to escape. Anna Anderson is the best known of several impostors who claimed to be the Grand Duchess Anastasia, daughter of the Tzar and heir to the Russian throne. She spent much of her life in mental institutions, always claiming to be Anastasia, until her death in 1984. Anastasia’s remains were later located and identified near the spot where her family was executed.
