Isabella de Beauchamp, Lady Kidwelly, Baroness Despenser (c. 1263 – before 30 May 1306), was an English noblewoman and wealthy heiress.
Lady Isabella, or Isabel de Beauchamp,[1] was born in about 1263 in Warwickshire, England.
She was the only daughter of William de Beauchamp, 9th Earl of Warwick and Matilda FitzJohn[1] who married sometime between 1261 and 1268; two sisters who were nuns at Shouldham are mentioned in her father's will.
Sometime before 1281, she married firstly Sir Patrick de Chaworth, Lord of Kidwelly in Carmarthenshire, South Wales.
Twenty years later, her husband and eldest son, favourites of King Edward II, were both executed by the orders of Roger Mortimer and Queen Isabella, who were by that time the de facto rulers of England; along with most of the people in the kingdom, they had resented the power both Despensers wielded over the King.
