    Earl of Northumberland. From Wikipedia:

    Henry Percy was originally a follower of Edward III of England, for whom he held high offices in the administration of northern England. At a young age he was made Warden of the Marches towards Scotland in 1362, with the authority to negotiate with the Scottish government. In February 1367 he was entrusted with the supervision of all castles and fortified places in the Scottish marches. He went on to support King Richard II and was created an Earl and briefly given the title of Marshal of England. Between 1383 and 1384 he was appointed Admiral of the Northern Seas. After Richard elevated his rival Ralph Neville to the position of Earl of Westmorland in 1397, Percy supported the rebellion of Henry Bolingbroke, who became King as Henry IV.

    On King Henry IV's coronation he was appointed Constable of England and granted the lordship of the Isle of Man. Percy and his son, Henry Percy, known as "Hotspur", were given the task of subduing the rebellion of Owain Glynd?r, but their attempts to make peace with the Welsh rebels did not meet with the king's approval.

    In 1403 the Percys turned against Henry IV in favour of Edmund Mortimer, 5th Earl of March, and then conspired with Owain Glynd?r against King Henry. The Tripartite Indenture was signed by all three parties, which divided England up between them. Glynd?r was to be given Wales, and a substantial part of the west of England, Northumberland was to have received the north of England, as well as Northamptonshire, Norfolk, Warwickshire, and Leicestershire. The Mortimers were to have received the rest of southern England, below the river Trent.

    The Percy rebellion failed at the Battle of Shrewsbury, where Hotspur was killed. Since the earl did not directly participate in the rebellion, he was not convicted of treason. However, he lost his office as Constable. In 1405 Percy supported Richard le Scrope, Archbishop of York, in another rebellion, after which Percy fled to Scotland, and his estates were confiscated by the king.

    In 1408 Percy invaded England in rebellion once more and was killed at the Battle of Bramham Moor. Percy's severed head was subsequently put on display at London Bridge.

    Earl of March. Earl of Ulster.

    From Wikipeia:

    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 on 24 August 1369 at the age of 17 to the 14-year-old Philippa, the only child of the late Lionel of Antwerp, Duke of Clarence, the second son of Edward III.

    Lionel's late wife, Elizabeth, had been daughter and heiress of William Donn de Burgh, 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. John of Gaunt, younger brother of Prince Edward, had become the 1st Duke of Lancaster and thus the source of the House of Lancaster's claim to the throne.

    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 between the Yorks and the Lancasters; Edward IV being descended from the second adult son of Edward III as great-great-grandson of Philippa, countess of March, and in the male line from Edmund of Langley, the first Duke of York and the fourth adult son of Edward III.

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

    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 House of Commons in this parliament was March's steward, Peter de la Mare, (1294-1387 of Little Hereford, Hereford), 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.

    Following the end of the Good Parliament its acts were reversed by John of Gaunt, March's steward was jailed, and March himself was ordered to inspect Calais and other remote royal castles as part of his duty as Marshal of England. March chose instead to resign the post.

    On the accession of Richard II, a minor, in 1377, the Earl became a member of the standing council of government; though as husband of the heir-presumptive to the crown he wisely abstained from claiming any actual administrative office. The richest and most powerful person in the realm was, however, the king's uncle John of Gaunt, whose jealousy led March to accept the office of Lord Lieutenant of Ireland in 1379. March succeeded in asserting his authority in eastern Ulster, but failed to subdue the O'Neills farther west. Proceeding to Munster to put down the turbulent southern chieftains, March was killed at Cork on 27 December 1381. He was buried in Wigmore Abbey, of which he had been a benefactor, and where his wife Philippa was also interred.
