In July 1991, nine skeletons were exhumed from a shallow mass grave near Ekaterinburg, Siberia. The site was a few miles from the Ipatiev House where the Tsar and his family, and retainers, had been murdered seventy-three years before. Authenticating these bones as those of the Romanovs added yet another chapter to the Russian Revolution of 1917. But when all the testing was done, and the bones were authenticated as those of the Russian royal family, it was discovered that two of the children were missing: one daughter and the son, Alexis, the tsarevich. Which daughter it was could not be determined but it was either Marie or Anastasia. After the bones were identified, fresh rumors persisted that Anna Anderson, who for sixty years had maintained she was Anastasia, really was the only surviving member of the royal family.
