Just ahead of revolutionary troops, they escaped to Novorossiysk, and took refuge in the residence of the Danish consul, Thomas Schytte, who informed them of the Dowager Empress's safe arrival in Denmark. After a brief stay with the consul, the family was shipped to a refugee camp on the island of Büyükada in the Dardanelles Strait near Istanbul, Turkey, where Olga, her husband and children shared three rooms with eleven other adults. After two weeks, they were evacuated to Belgrade in the Kingdom of Serbs, Croats and Slovenes where she was visited by Prince Regent Alexander. Alexander offered the Grand Duchess and her family a permanent home, but Olga was summoned to Denmark by her mother. On Good Friday 1920, Olga and her family arrived in Copenhagen. They lived with the Dowager Empress, at first at the Amalienborg Palace and then at the royal estate of Hvidøre, where Olga acted as her mother's secretary and companion. It was a difficult arrangement at times. The Dowager Empress insisted on having Olga at her beck and call and found Olga's young sons too boisterous. Having never reconciled with the idea of her daughter's marriage to a commoner, she was cold towards Kulikovsky, rarely allowing him in her presence. At formal functions, Olga was expected to accompany her mother alone. In 1925, Olga and Colonel Kulikovsky travelled to Berlin to meet Anna Anderson, who claimed to be Olga's niece, Grand Duchess Anastasia Nikolaevna of Russia. Anderson had attempted suicide in Berlin in 1920, which Olga later called "probably the only indisputable fact in the whole story". Anderson claimed that with the help of a man named Tchaikovsky she had escaped from revolutionary Russia via Bucharest, where she had given birth to his child. Olga thought the story "palpably false", since Anderson made no attempt to approach Queen Marie of Romania, during her entire alleged time in Bucharest. Olga said: Anderson stated she was in Berlin to inform Princess Irene of Prussia (sister of Tsarina Alexandra and cousin of Tsar Nicholas II) of her survival. Olga commented, "[Princess Irene] was one of the most straightlaced women in her generation. My niece would have known that her condition would have indeed have shocked [her]." Olga met Anderson, who was being treated for tuberculosis, at a nursing home.
