stronger royal ties to the claims of the Tudor dynasty. Owen and Catherine had at least six children. Edmund, Jasper, and Edward were all born away from court. They had one daughter, Margaret, who became a nun and died young. Death and aftermath Catherine died on 3 January 1437, shortly after childbirth, in London, and was "buried in the old Lady chapel" of Westminster Abbey. While the death date is not in question, the cause is, with an equal number of records stating that she did not die as a result of childbirth, but entered Bermondsey Abbey, possibly seeking a cure for an illness that had troubled her for some time. She made her will just three days before her death. She now rests at Westminster Abbey in Henry V's Chantry Chapel. After her death, Catherine's enemies decided to proceed against Owen for violating the law of the remarriage of the queen dowager. Owen appeared before the council, was subsequently arrested, and taken to Newgate Prison. He tried to escape from Newgate Prison in early 1438 and eventually ended up at Windsor Castle in July of that year. 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. The wooden funeral effigy which was carried at Catherine's funeral still survives at Westminster Abbey, and was previously on display in the Westminster Abbey Museum in the Undercroft. It is now displayed in the new Queen's Diamond Jubilee Gallery in the abbey triforium. Her tomb originally boasted an alabaster memorial, which was deliberately destroyed during extensions to the abbey in the reign of her
