Anna Anderson could not be related to Tsar Nicholas or Tsarina Alexandra." Anderson's mitochondrial DNA was a match with a great-nephew of Franziska Schanzkowska, a missing Polish factory worker. Some supporters of Anderson's claim acknowledged that the DNA tests proving she could not have been the Grand Duchess had "won the day". Other lesser known claimants were Nadezhda Ivanovna Vasilyeva and Eugenia Smith. Two young women claiming to be Anastasia and her sister Maria were taken in by a priest in the Ural Mountains in 1919 where they lived as nuns until their deaths in 1964. They were buried under the names Anastasia and Maria Nikolaevna. Rumors of Anastasia's survival were embellished with various contemporary reports of trains and houses being searched for "Anastasia Romanov" by Bolshevik soldiers and secret police.

Russia had recently signed a peace treaty with the Germans, and did not want to upset them by letting them know the women were dead, so they told them they had been moved to a safer location.

These witnesses were Maxim Grigoyev, Tatiana Sitnikova (and her son Fyodor Sitnikov), Ivan Kuklin and Matrina Kuklina, Vassily Ryabov, Ustinya Varankina, and Dr Pavel Utkin, a physician who treated the girl after the incident. Some of the witnesses identified the girl as Anastasia when they were shown photographs of the grand duchess by White Russian Army investigators. Utkin also told the White Russian Army investigators that the
