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.
Margaret of York (1472)

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.
