Aurora Stjernvall was born in Pori on August 1, 1808. Following the death of her father, the provincial governor Carl Johan Stjernvall, Aurora was sent to St. Petersburg at the age of eight to be raised by her aunt. In 1820 her stepfather, C.J. Walleen was appointed senator and the family moved to Helsinki. During Emperor Nicholas I's visit to Helsinki, Aurora acted as a lady-in-waiting to the imperial entourage. Three years later she was invited to St. Petersburg to receive the official title of lady-in-waiting.
      Aurora was married twice. Her first husband was the Russian, Paul Demidov, Hunt Master to the Imperial Court.

They had a son, Paul, in 1839 but in the following year her husband died in the Rhineland. She embarked on her second marriage in St. Petersburg with Colonel Andrei Karamzin. Even this second marriage was short lived, as Andrei fell in the Crimean war in 1854. During the later part of her life, Aurora faced many hardships. In addition to her second husband's death, she faced the death of Paul, her only child, in 1885. The fire at the Träskända manorhouse in the autumn of 1888 was a further cause for grief. Aurora Karamzin died in the Hakasalmi Villa on May 13, 1902.
