The de Clare sisters Eleanor, Margaret and Elizabeth were born in the 1290s as the eldest granddaughters of King Edward I of England and his Spanish queen Eleanor of Castile, and were the daughters of the greatest nobleman in England, Gilbert ‘the Red’ de Clare, earl of Gloucester. They grew to adulthood during the turbulent reign of their uncle Edward II, and all three of them were married to men involved in intense, probably romantic or sexual, relationships with their uncle.
