Her youngest child, Joan Neville (neé Beaufort), Countess of Westmorland, was buried with her many years later.

On 10th May 1645, the besieging Parliamentarians made a new work on Monkhill. The work was in the form of a half moon or crescent shape and afforded protection to the besiegers but constantly annoyed the besieged Royalists. If they made a sally up Northgate, they were exposed to the fire from the Parliamentary forces from Monkhill. The following day, a strong fire was kept up on both sides. The besieged observed the enemy send three or four wagons loaded with goods in the direction of Ferrybridge. This led them to believe the besiegers were getting ready to depart. Strengthening their belief was the sight of sheep and cattle being driven along the same road the following day. It was found afterwards that the wagons and animals were being sent to York to supply the troops there. The besiegers received on the same day a reinforcement of a troop of horse from Doncaster, which joined the main guard at the New Hall. - Sandal Castle 14th Century
