Olga escaped revolutionary Russia with her second husband and their two sons in February 1920. They joined her mother, the Dowager Empress, in Denmark. In exile, Olga acted as companion and secretary to her mother, and was often sought out by Romanov impostors who claimed to be her dead relatives. She met Anna Anderson, the best-known impostor, in Berlin in 1925. After the Dowager Empress's death in 1928, Olga and her husband purchased a dairy farm in Ballerup, near Copenhagen. She led a simple life: raising her two sons, working on the farm and painting. During her lifetime, she painted over 2,000 works of art, which provided extra income for both her family and the charitable causes she supported.
