  Research Notes:

From Wikipedia - Isabel le Despenser, Countess of Arundel :

Isabel le Despenser (1312 - 1356) was the eldest daughter of Hugh the younger Despenser and Eleanor de Clare . Her father is famous for being the favorite of Edward II of England .

Early Life
After their father was executed for treason in 1326, Isabel and her youngest sister Elizabeth le Despenser were the only daughters of Hugh the Younger to escape being confined in nunneries, Isabel because she was already married and Elizabeth because of her youth.

Marriage and Annulment
On 9 February 1321 Isabel was married to Richard Fitzalan , the heir to the earldom of Arundel.
Richard and Isabel had one son, Edmund Fitzalan, born in 1327, and in 1331 Isabel's husband became earl of Arundel . However in December 1344 Richard Fitzalan had their marriage annulled on the grounds that he had never freely consented to marry Isabel. Isabel retired to several manors in Essex that were given to her by her ex-husband.

Richard and Isabel's only child, Edmund Fitzalan, was rendered illegitimate by this annulment and so was unable to inherit his father's earldom. When his father died in 1376 Edmund quarrelled with his half-siblings, the children of his father's second marriage, over inheritance rights. Edmund was imprisoned in the Tower of London until he was released in 1377 by request of his brothers-in-law.

Isabel married Sir Richard "Copped Hat" FitzAlan 10th Earl of Arundel and Warenne, son of Sir Edmund FitzAlan 9th Earl of Arundel and Alice de Warenne, on 9 Feb 1321. (Sir Richard "Copped Hat" FitzAlan 10th Earl of Arundel and Warenne was born about 1313, died on 24 Jan 1376 in Arundel, West Sussex, England and was buried in Lewes Priory, Lewes, Sussex, England.)
