She began calling herself Anna Tschaikovsky, choosing "Anna" as a short form of "Anastasia", although Peuthert "described her everywhere as Anastasia". Tschaikovsky stayed in the houses of acquaintances, including Kleist, Peuthert, a poor working-class family called Bachmann, and at Inspector Grünberg's estate at Funkenmühle, near Zossen. At Funkenmühle, Grünberg arranged for the Tsarina's sister, Princess Irene of Hesse and by Rhine, to meet Tschaikovsky, but Irene did not recognize her. Grünberg also arranged a visit from Crown Princess Cecilie of Prussia, but Tschaikovsky refused to speak to her, and Cecilie was left perplexed by the encounter. Later, in the 1950s, Cecilie signed a declaration that Tschaikovsky was Anastasia, but Cecilie's family disputed her statement and implied that she was suffering from dementia.
