1. Elizabeth MORTIMER, daughter of Edmund Mortimer, 3rd Earl of March (1351-1381) and Philippa Plantagenet of Clarence (1355- ), married Henry Percy (Harry Hotspur).

 

Henry Percy (Harry Hotspur) and Elizabeth MORTIMER had the following children:

 

Elizabeth PERCY (c. 1390-1437). Elizabeth was born circa 1390. She married in 1404. She married John CLIFFORD in 1404. She died on 26 October 1437.

Second Generation

2. Edmund Mortimer, 3rd Earl of March was born in 1351. He died on 17 December 1381. He married Philippa Plantagenet of Clarence.

 

Edmund de Mortimer, 3rd Earl of March

Edmund de Mortimer, 3rd Earl of March and jure uxoris Earl of Ulster (1351? – 27 December, 1381) was son of Roger Mortimer, 2nd Earl of March, by his wife Philippa, daughter of William Montacute, 1st Earl of Salisbury.

Early life

Being an infant at the death of his father, Edmund, as a ward of the crown, was placed by Edward III of England under the care of William of Wykeham and Richard Fitzalan, 10th Earl of Arundel.

The position of the young earl, powerful on account of his possessions and hereditary influence in the Welsh marches, was rendered still more important by his marriage in 1368 at the age of 17 to the 13 year old Philippa, the only child of Lionel of Antwerp, Duke of Clarence, third son of Edward III.

Lionel's wife, Elizabeth, was daughter and heiress of William de Burgh, 6th Lord of Connaught and 3rd Earl of Ulster, and Lionel had himself been created Earl of Ulster before his marriage. Edmund inherited the title Earl of Ulster on Lionel's death.

Therefore, the Earl of March not only represented one of the chief Anglo-Norman lordships in Ireland in right of his wife Philippa, but Philippa's line was also the second most senior line of descent in the succession to the crown, after Edward, the Black Prince and his son, King Richard II of England.

This marriage had, therefore, far-reaching consequences in English history, ultimately giving rise to the claim of the House of York to the crown of England contested in the Wars of the Roses; Edward IV being descended from the third son of Edward III as great-great-grandson of Philippa, countess of March, and in the male line from Edmund of Langley, fifth son of Edward III.

Edmund's son Roger Mortimer, 4th Earl of March would become heir presumptive to the English crown during the reign of Richard II.

Political Advancement

Mortimer, now styled Earl of March and Ulster, became Marshal of England in 1369, and was employed in various diplomatic missions during the next following years. He was a member of the committee appointed by the Peers to confer with the Commons in 1373?the first instance of such a joint conference since the institution of representative parliaments on the question of granting supplies for John of Gaunt's war in France.

He participated in the opposition to Edward III and the court party, which grew in strength towards the end of the reign, taking the popular side and being prominent in the Good Parliament of 1376 among the lords who supported the Prince of Wales and opposed the Court Party and John of Gaunt. The Speaker of the Commons in this parliament was March's steward, Peter de la Mare, who firmly withstood John of Gaunt in stating the grievances of the Commons, in supporting the impeachment of several high court officials, and in procuring the banishment of the king's mistress, Alice Perrers. March was a member of the administrative council appointed by the same parliament after the death of Edward, the Black Prince to attend the king and advise him in all public affairs.

Third Generation

4. Lionel of Antwerp DUKE OF CLARENCE, son of Edward III KING OF ENGLAND and Philippa de Hainault, 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.

 

5. Elizabeth de Burgh, daughter of William de Burgh, 6th Lord of Connaught and 3rd Earl of Ulster, was born in 1332. She died in 1363 in Dublin. She and Lionel of Antwerp DUKE OF CLARENCE had the following children:
