Overview
Eleanor of Lancaster, Countess of Arundel (sometimes called Eleanor Plantagenet; 11 September 1318 – 11 January 1372) was the fifth daughter of Henry, 3rd Earl of Lancaster and Maud Chaworth.
First marriage and issue
Eleanor married first on 6 November 1330 John de Beaumont, 2nd Baron Beaumont (d. 1342), son of Henry Beaumont, 4th Earl of Buchan, 1st Baron Beaumont (c.1288-1340) by his wife Alice Comyn (1289-3 July 1349). He died in a tournament on 14 April 1342. They had one son, born to Eleanor in Ghent whilst serving as lady-in-waiting to Queen Philippa of Hainault:
Henry Beaumont, 3rd Baron Beaumont, (4 April 1340 – 25 July 1369), the first husband of Lady Margaret de Vere (d. 15 June 1398), the daughter of John de Vere, 7th Earl of Oxford by his wife Maud de Badlesmere. Henry and Margaret had one son, John Beaumont, 4th Baron Beaumont KG (1361-1396).
Second marriage
On 5 February 1345 at Ditton Church, Stoke Poges, Buckinghamshire, she married Richard FitzAlan, 3rd Earl of Arundel.
His previous marriage, to Isabel le Despenser, had taken place when they were children. It was annulled by Papal mandate as she, since her father's attainder and execution, had ceased to be of any importance to him. Pope Clement VI obligingly annulled the marriage, bastardized the issue, and provided a dispensation for his second marriage to the woman with whom he had been living in adultery (the dispensation, dated 4 March 1345, was required because his first and second wives were first cousins).
