Elizabeth of York, Duchess of Suffolk

Elizabeth of York, Duchess of Suffolk also known as Elizabeth Plantagenet (22 April 1444 – c. 1503) was the sixth child and third daughter of Richard Plantagenet, 3rd Duke of York (a great-grandson of King Edward III) and Cecily Neville. She was thus a sister of kings Edward IV and Richard III.

Marriage
Sometime before February 1458, Elizabeth was married to John de la Pole. John was the eldest son of William de la Pole, 1st Duke of Suffolk and Alice Chaucer. His maternal grandparents were Thomas Chaucer and Maud Burghersh.

Her father-in-law had served as the principal power behind the throne for Henry VI of England from 1447 to 1450. His three years in this position saw the near-complete loss of the English possessions in northern France, towards the end of Hundred Years' War. Suffolk could not avoid taking the fall for the failure. He had been imprisoned in the Tower of London and had been attainted. Consequently, John had not succeeded to his titles when his father was executed on 2 May 1450.

Her older brother Edward IV of England restored his brother-in-law to the title of Duke of Suffolk in 1463. She remained the Duchess of Suffolk until his death in 1491/1492. They were settled in Wingfield, Suffolk.

She survived her husband by almost a decade. She is last mentioned alive in January 1503. She was mentioned being deceased by May 1504. She is buried in the church in Wingfield, Suffolk.
