Isabel Neville (or Isabella) (September 5, 1451-December 22, 1476) was the elder daughter of Richard Neville, 16th Earl of Warwick, the "Kingmaker" of the Wars of the Roses, and Anne Neville, 16th Countess of Warwick and the wife of George, Duke of Clarence. She was also the elder sister of Anne Neville Queen Consort to Richard III.

Marriage

Isabel was born at Warwick Castle the seat of the Earls of Warwick. In 1469, her ambitious father engaged her to England's heir apparent, George, Duke of Clarence brother to both Edward IV of England and Richard, Duke of Gloucester (later Richard III). The king was against the marriage as this would bring the already powerful Warwick too close to the throne. The ceremony took place in secret at Calais on 11 July 1469, conducted by Isabel's relation George Neville, Archbishop of York.

Following their marriage Clarence joined forces with Warwick and traitorously allied with the Lancastrians led by Margaret of Anjou Queen Consort to Henry VI. After Isabella's sister Anne was married to Edward of Westminster the son and heir of Henry VI Clarence rejoined his brother, realising that it was now unlikely that he would become king.

Isabel's first child was either stillborn or died shortly after its birth at sea. In 1473, she gave birth to a daughter called Margaret and in 1475 to a son called Edward. Isabel died the next year either from consumption or childbed fever.
