Which Warwickshire castle was the birthplace of Isabel Neville, Duchess of Clarence?

Warwick Castle was the Warwickshire castle where Isabel Neville, Duchess of Clarence, was born.

Isabel Neville was born on 5 September 1451 at Warwick Castle, the principal seat of her father, Richard Neville, 16th Earl of Warwick. Her mother was Anne de Beauchamp, suo jure Countess of Warwick. Isabel and her younger sister Anne became heiresses to a vast Neville and Beauchamp inheritance after the deaths of their parents.

Her marriage made her central to the politics of the Wars of the Roses. In 1469 she married George Plantagenet, Duke of Clarence, the younger brother of Edward IV. Her father Warwick later allied with Clarence against Edward, and Isabel’s marriage helped connect the Neville family’s power with a rival branch of the Yorkist royal family.

Middleham Castle is an understandable distractor because it was an important Neville stronghold and was closely associated with Richard of Gloucester, later Richard III. Kenilworth and Ludlow were also major medieval castles, but neither was Isabel’s recorded birthplace.
