The farm became a center for the Russian monarchist community in Denmark, and many Russian emigrants visited. Olga maintained a high level of correspondence with the Russian émigré community and former members of the imperial army. On 2 February 1935 in the Russian Orthodox Church in Copenhagen, she and her husband were godparents, with her cousin Prince Gustav of Denmark, to Aleksander Schalburg, son of Russian-born Danish army officer Christian Frederik von Schalburg. In the 1930s, the family took annual holidays at Sofiero Castle, Sweden, with Crown Prince Gustaf of Sweden and his wife, Louise. Olga began to sell her own paintings, of Russian and Danish scenes, with exhibition auctions in Copenhagen, London, Paris, and Berlin. Some of the proceeds were donated to the charities she supported.
