The fourth child of St. Bridget and her husband, Ulf Gudmarsson, born 1331 or 1332; died 24 March, 1381. At the time of her death St. Catherine was head of the convent of Wadstena, founded by her mother; hence the name, Catherine Vastanensis, by which she is occasionally called. At the age of seven she was sent to the abbess of the convent of Riseberg to be educated and soon showed, like her mother, a desire for a life of self-mortification and devotion to spiritual things. At the command of her father, when about thirteen or fourteen years, she married a noble of German descent, Eggart von Kürnen. She at once persuaded her husband, who was a very religious man, to join her in a vow of chastity. Both lived in a state of virginity and devoted themselves to the exercise of Christian perfection and active charity. In spite of her deep love for her husband, Catherine accompanied her mother to Rome, where St. Bridget went in 1349. Soon after her arrival in that city Catherine received news of the death of her husband in Sweden. She now lived constantly with her mother, took an active part in St. Bridget's fruitful labours, and zealously imitated her mother's ascetic life. Although the distinguished and beautiful young widow was surrounded by suitors, she steadily refused all offers of marriage. In 1372 St. Catherine and her brother, Birger, accompanied their mother on a pilgrimage to the Holy Land; after their return to Rome St. Catherine was with her mother in the latter's last illness and death.
