George Plantagenet, 1st Duke of Bedford

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.
Margaret of York (1472)
Margaret of York( 10 April 1472 – 11 December 1472) was a namesake niece of Margaret of York, Duchess of Burgundy.

She was born in Winchester Castle but died of natural causes eight months later.
She was buried in Westminster Abbey.
Margaret's sarcophagus was originally placed to fit in the steps of the shrine of St. Edward the Confessor, but it was moved to the edge of the chapel at the time of the dissolution of the monasteries.
The step edging around the sides can, however, still be seen.
An annotated history of the Abbey in the Abbey's library states that the lid was removed in more modern times and the sarcophagus found to be empty.
The monumental brass originally on the top of Margaret's tomb is long since missing, but the original wording around the edge and on the surface plaque was recorded historically.
Elizabeth Woodville
Elizabeth Woodville (also spelled Wydville, Wydeville, or Widvile) (c. 1437 – 8 June 1492) was Queen consort of England, as the spouse of King Edward IV from 1464 until his death in 1483.
At the time of her birth, her family was of middle rank in the English social hierarchy.
Her mother Jacquetta of Luxembourg had previously been an aunt by marriage to Henry VI.
Elizabeth's first marriage was to a minor supporter of the House of Lancaster, Sir John Grey of Groby.
He died at the Second Battle of St Albans, leaving Elizabeth a widowed mother of two sons.
Her second marriage to Edward IV was a cause célèbre of the day, thanks to Elizabeth's great beauty and lack of great estates.
Edward was the first king of England since the Norman Conquest to marry one of his subjects, and Elizabeth was the first such consort to be crowned queen.
Her marriage greatly enriched her siblings and children, but their advancement incurred the hostility of Richard Neville, Earl of Warwick, 'The Kingmaker', and his various alliances with the most senior figures in the increasingly divided royal family.
This hostility turned into open discord between King Edward and Warwick, leading to a battle of wills that finally resulted in Warwick switching allegiance to the Lancastrian cause, and to the execution of Elizabeth's father Richard Woodville in 1469.
After the death of her husband in 1483, Elizabeth remained politically influential even after her son, briefly proclaimed King Edward V of England, was deposed by her brother-in-law, Richard III.
Edward and his younger brother Richard both disappeared soon afterward, and are presumed to have been murdered.
Elizabeth subsequently played an important role in securing the accession of Henry VII in 1485.
Henry married her daughter Elizabeth of York, ended the Wars of the Roses, and established the Tudor dynasty.
Through her daughter, Elizabeth was a grandmother of the future Henry VIII.
Elizabeth was forced to yield pre-eminence to Henry VII's mother, Lady Margaret Beaufort; her influence on events in these years, and her eventual departure from court into retirement, remains obscure.
