Margery (Margaret) le Despenser, de jure suo jure 3rd Baroness le Despenser (1387 creation), was the daughter and heiress of Philip le Despenser, 2nd Baron le Despenser. She was born about 1397 in Nettlestead, Suffolk, England, and married John de Ros, 7th Baron de Ros. He died without heirs, and she married secondly Roger Wentworth of Nettlestead, Esq. (d.1452), son of John Wentworth of North Elmsall.
Ethel Seaton writes:<blockquote>Lord John RoosâÂÂs wife, Margery Despenser, did not mourn her husband for long; it is true that she could have seen little of him. In less than a year from the day of Baugé, she married <mark>Roger</mark> Wentworth of Elmsall, armiger, âÂÂdishonourably and without licence from the kingâÂÂ. It is possible that her undistinguished choice alienated her from her Roos connexions more than did her haste to remarry. She seems to have become entirely a Wentworth, devoted to her son Philip; at the same time, she retained her Roos name and title. Her will of 1478 has no mention of Roos though her youngest brother-in-law, Sir Richard, was still alive. The only memorable thing about her is her patronage, in the wake of Margaret of Anjou and Elizabeth Wydville, of Queensâ College, Cambridge. There she founded a Fellowship c. 1470, and in 1472 made gifts to the Chapel, where she wished to be buried. At her death in April 1478, she left to its President, Andrew Dokett, a covered goblet, âÂÂcum Armis dni. de Roosâ (P.C.C. Wills, Wattys 33). She and her first husband and her youngest brother-in-law are all remembered, together with many royal persons, in the âÂÂCommemoration of Benefactorsâ of the College.</blockquote>For marrying "dishonourably without license from the king" before 2 March 1422/3 Roger Wentworth, Esq., younger son of John Wentworth, of Elmsall, Yorkshire, Margery was ordered to pay a fine of at least ã1000 for having married "so far beneath her."
