Katherine Swynford

Katherine Swynford, Duchess of Lancaster (born Katherine de Roet, – 10 May 1403), also spelled Katharine or Catherine, was the third wife of John of Gaunt, Duke of Lancaster, the fourth (but third surviving) son of King Edward III. Daughter of a knight from Hainaut, Katherine was brought up at the English royal court, later found herself in the service of Blanche of Lancaster, the first wife of John of Gaunt. At that time, she was married to Hugh Swynford (or de Swynford), one of the Duke's knights. After the death of the Duchess, Katherine became the lady-in-waiting of her daughters, and also took care of them. After the death of Hugh Swynford (or de Swynford), she became a member of the household of the Duke's new wife, Constance of Castile, and she was given management of the estates of her deceased husband in Lincolnshire: Coleby and Kettlethorpe. She soon became the mistress of John of Gaunt. From this connection, at least four children were born, who received the surname Beaufort after one of their father's French estates. Those four children were later recognized and legitimized by the Church. In addition, Gaunt gave his mistress several estates, and also provided her with a generous allowance. Since the relationship between Katherine and John of Gaunt caused public condemnation, in 1381 the Duke was forced to break their relationship. Katherine then settled in a rented house in Lincoln.
