Around 1210, Helena Sverkersdotter, the only daughter of the deposed King Sverker II, was studying at the Vreta convent when her father fell in battle.
The young Sune Folkason, son of an earl who had been among Sverker's opponents in that battle and had also fallen, wished to marry her, but her relatives would not hear his proposal.
Around 1244, Benedikte Sunadotter, the younger daughter of Sune Folkason and Helena Sverkersdotter, was being educated at the Vreta convent.
In any case, Benedikte was released and soon married high noble Svantepolk Knutsson, Lord of Viby, with whom she had several daughters and a son, Knut, who died childless.
King Magnus Ladulås, reportedly livid about the wilful breach of women's safety in convents, had one of the brothers executed.
