Cine s-a căsătorit cu Catherine of Ymseborg?

Katarina Sunesdotter (c. 1215 – 1252), also known as Karin, was Queen of Sweden from 1244 to 1250 as the wife of King Erik Eriksson. In her later years she served as abbess of Gudhem Abbey in Falbygden.

Erik Eriksson (Old Norse: Eiríkr Eiríksson; 1216 – 2 February 1250), sometimes known as Erik XI or with the epithet the Lisp and Lame (läspe och halte), was King of Sweden from 1222 to 1229 and again from 1234 to 1250. Being the last ruler of the House of Erik, he stood in the shadow of a succession of powerful jarls, especially his brother-in-law Birger Jarl, whose descendants ruled as kings after his death.
