She was educated privately at home, and then two years at a finishing school, the fashionable Bjurströmska flickpensionen (Bjurström's Pension for Girls) in Stockholm. In 1869, she married the nobleman colonel lieutenant Axel Adlersparre (1812–1879), by whom she became the stepmother of five children.
