Lionel DUKE OF CLARENCE (1338-1368)

1. Lionel of Antwerp DUKE OF CLARENCE, son of Edward III KING OF ENGLAND (1312-1377) and Philippa de Hainault (1311-1369), was born on 29 November 1338 in Antwerp, Holland. He died on 7 October 1368 in Alba, Italy. He married Elizabeth de Burgh.


Lionel of Antwerp, Duke of Clarence (November 29, 1338 ?October 7, 1368) was the second son of Edward III of England and Philippa of Hainault. He was so called because he was born at Antwerp, Belgium.

Betrothed when a child to Elizabeth de Burgh, 4th Countess of Ulster (d. 1363), daughter and heiress of William Donn de Burgh, 3rd Earl of Ulster (d. 1332), he was married to her in 1352, but before this date he had entered into possession of her great Irish inheritance. He was called Earl of Ulster from 1347.

Having been named as his father's representative in England in 1345 and again in 1346, Lionel joined an expedition into France in 1355, but his chief energies were reserved for the affairs of Ireland.

Appointed governor of that country, he landed at Dublin in 1361, and in November of the following year was created Duke of Clarence, while his father made an abortive attempt to secure for him the crown of Scotland. His efforts to secure an effective authority over his Irish lands were only moderately successful; and after holding a parliament at Kilkenny, which passed the celebrated Statute of Kilkenny in 1367, he dropped the task in disgust and returned to England.

Lionel's wife died in Dublin in 1363, leaving behind a daughter, Philippa, whose descendants would one day claim the throne for the House of York. A second marriage was arranged for Lionel with Yolande or Violante, daughter of Galeazzo Visconti, lord of Pavia (d. 1378); the enormous dowry which Galeazzo promised with his daughter being exaggerated by the rumour of the time. Journeying to fetch his bride, Lionel was received in great state both in France and Italy, and was married to Violante at Milan in June 1368. Some months were then spent in festivities, during which Lionel was taken ill at Alba, where he died. There was strong speculation at the time that he had been poisoned by his father-in-law [1] although this has never been proven.

His only child, Philippa Plantagenet, married in 1368 Edmund Mortimer, 3rd Earl of March (1351-1381). They were grandparents to Anne Mortimer, great-grandparents to Richard Plantagenet, 3rd Duke of York and great-great-grandparents to Edward IV and Richard III.

The poet Geoffrey Chaucer was at one time a page in Lionel's household.

Mortimer, Sir Edmund de, 1376–1409, English nobleman; youngest son of Edmund de Mortimer, 3rd earl of March. In 1398 when young Edmund, the 5th earl, nephew of Sir Edmund, succeeded to the title while still a minor, Sir Edmund became the most powerful representative of his family. He supported the usurpation of the throne by the Lancastrian Henry IV in 1399. In 1402, however, Mortimer was captured by the rebellious Welshman Owen Glendower, and when the suspicious king forbade his ransom, Edmund entered an alliance with Glendower and married his daughter. Supporting the claim of his young nephew to the throne, he and Glendower continued to fight even after the defeat of their allies, the Percy family (see Percy, Sir Henry and Northumberland, Henry Percy, 1st earl of). However, Glendower began to suffer defeats, Mortimer's own effectiveness declined, and he died when besieged by royal forces at Harlech.
