Claim: Sophia of Denmark's sisters Agnes and Jutta escaped a convent and fled to the Swedish Royal court, and Jutta had an affair with King Valdemar,  the son of the Swedish princess Ingeborg Eriksdotter and Birger Jarl.
Evidence: In 1271, Agnes and Jutta escaped from the convent in Roskilde and fled to their sister Queen Sophia in Sweden. They were kindly welcomed at the Swedish royal court, but Jutta and Valdemar made a scandal by having an affair. Valdemar was the son of the Swedish princess Ingeborg Eriksdotter and Birger Jarl, from the House of Bjelbo.
