From 1904 to 1906 Duke Peter had an appointment to a military post in Tsarskoye Selo, a complex of palaces just south of Saint Petersburg. In Tsarskoye Selo, the Grand Duchess grew close to her brother Nicholas and his family, who lived at the Alexander Palace near her own residence. Olga prized her connection to the Tsar's four daughters. From 1906 to 1914, Olga took her nieces to parties and engagements in Saint Petersburg, without their parents, every weekend throughout the winter. She especially took a liking to the youngest of Nicholas's daughters, her god-daughter Anastasia, whom she called "Shvipsik" ("little one"). Through her brother and sister-in-law, Olga met Rasputin, a self-styled holy man who purported to have healing powers. Although she made no public criticisms of Rasputin's association with the imperial family, she was unconvinced of his supposed powers and privately disliked him. As Olga grew close to her brother's family, her relationship with her other surviving brother, Michael, deteriorated. To her and Nicholas's horror, Michael eloped with his mistress, a twice-divorced commoner, and communication between Michael and the rest of the family essentially ceased.
