During Katherine de la Pole's time as abbess, the young Edmund and Jasper Tudor were sent to be brought up in the abbess's custody by King Henry VI's council. The boys were Henry VI's half brothers: the children of Owen Tudor and Catherine of Valois; herself the widow of King Henry V and Henry VI's mother. The Tudors were raised and educated at Barking under the care of Abbess Katherine. An allowance of £52 12s () was paid for their maintenance. Edmund went on to father King Henry VII, who seized the throne at the Battle of Bosworth in 1485.
