Meanwhile, Owen and Catherine's two older sons, Edmund and Jasper, went to live with Katherine de la Pole, Abbess of Barking and sister of William de la Pole, 1st Duke of Suffolk. Sometime after 1442, the king (their half-brother) took a role in their upbringing. Owen, their father, was eventually released on £2000 bail, but was pardoned in November 1439 (and the bail cancelled in 1440). Owen was treated well afterwards and was a member of the king's household until the mid-1450s. He lived until 1461, when he was executed by the Yorkists following the Battle of Mortimer's Cross in Herefordshire. Their sons were given earldoms by Catherine's son King Henry VI. Edmund married Margaret Beaufort, a descendant of John of Gaunt who had consequently a distant but disputed claim to the throne; following the elimination by war of most other candidates, their son became King Henry VII.
