Ipatiev House
There have been numerous post-Revolution reports of Romanov survivors and unsubstantiated claims by individuals to be members of the deposed Tsar Nicholas II's family, the best known of whom was Anna Anderson. Proven research has, however, confirmed that all of the Romanovs held prisoners inside the Ipatiev House in Ekaterinburg were killed. Descendants of Nicholas II's two sisters, Grand Duchess Xenia Alexandrovna of Russia and Grand Duchess Olga Alexandrovna of Russia, do survive, as do descendants of previous tsars.
