Edward, 2nd Duke of York
Edward, 2nd Duke of York, , (– 25 October 1415) was an English nobleman and magnate, the eldest son of Edmund of Langley, 1st Duke of York, and a grandson of King Edward III of England.
He held significant appointments during the reigns of Richard II, Henry IV, and Henry V, and is also known for his translation of the hunting treatise "The Master of Game".
He was slain at the Battle of Agincourt, one of the principal military engagements of the Hundred Years' War against France, in 1415.
Richard of Conisburgh, 3rd Earl of Cambridge
Richard of Conisburgh, 3rd Earl of Cambridge( c. July 1385 – 5 August 1415) was the second son of Edmund of Langley, 1st Duke of York, and Isabella of Castile.
He was beheaded for his part in the Southampton Plot, a conspiracy against King Henry V.
He was the father of Richard Plantagenet, 3rd Duke of York, and the grandfather of King Edward IV and King Richard III.
Edward III of England
Edward III (13 November 1312 – 21 June 1377) was king of England and Lord of Ireland from January 1327 until his death; he is noted for his military success and for restoring royal authority after the disastrous and unorthodox reign of his father, Edward II.
Edward III transformed the Kingdom of England into one of the most formidable military powers in Europe.
His long reign of 50 years was the second-longest in medieval England (after that of his great-grandfather Henry III) and saw vital developments in legislation and government, in particular the evolution of the English Parliament, as well as the ravages of the Black Death.
Edward was crowned at age fourteen after his father was deposed by his mother, Isabella of France, and her lover Roger Mortimer.
At age seventeen he led a successful coup d'état against Mortimer, the de facto ruler of the country, and began his personal reign.
After a successful campaign in Scotland he declared himself rightful heir to the French throne in 1337.
This started what became known as the Hundred Years' War.
Following some initial setbacks, this first phase of the war went exceptionally well for England; victories at Crécy and Poitiers led to the highly favourable Treaty of Brétigny, in which England made territorial gains, and Edward renounced his claim to the French throne.
This phase would become known as the Edwardian War.
Edward's later years were marked by international failure and domestic strife, largely as a result of his inactivity and poor health.
Edward III was a temperamental man but capable of unusual clemency.
He was in many ways a conventional king whose main interest was warfare.
Admired in his own time and for centuries after, Edward was denounced as an irresponsible adventurer by later Whig historians such as William Stubbs, but modern historians credit him with some significant achievements.
James FitzJames, 1st Duke of Berwick
James FitzJames, 1st Duke of Berwick, 1st Duke of Liria and Jérica, 1st Duke of Fitz- James( 21 August 1670 – 12 June 1734) was an Anglo- French military leader, illegitimate son of King James II of England by Arabella Churchill, sister of the 1st Duke of Marlborough.
Berwick was a successful general in the pay of Louis XIV of France.
George Plantagenet, 1st Duke of Bedford
George of York, 1st Duke of Bedford( March 1477 – March 1479) was the eighth child and third son of Edward IV of England and Elizabeth Woodville.
He was a younger brother of Elizabeth of York, Mary of York, Cecily of York, Edward V of England, Margaret Plantagenet, Richard of Shrewsbury, 1st Duke of York and Anne of York.
He was also an older brother of Catherine of York and Bridget of York.
He was born in Windsor Castle in March 1477, and was created Duke of Bedford in infancy, probably in 1478, after the former holder of the title, George Neville, was deprived of the title by act of Parliament, ostensibly for lack of money to maintain the style of a duke.
He was appointed the Lord Lieutenant of Ireland in 1478, one of a series of nominal and largely absent lieutenants.
George died aged two.
This is considered likely to have been due to an outbreak of bubonic plague.
He was buried in St George's Chapel at Windsor Castle on March 22, 1479.
Edmund of Langley, 1st Duke of York
Edmund of Langley, 1st Duke of York, KG (5 June 13411 August 1402) was the fourth surviving son of King Edward III of England and Philippa of Hainault.

He was the founder of the House of York, but it was through the marriage of his younger son, Richard of Conisburgh, 3rd Earl of Cambridge, to Anne de Mortimer, great-granddaughter of Edmund's elder brother Lionel of Antwerp, 1st Duke of Clarence, that the House of York made its claim to the English throne in the Wars of the Roses.
