Elizabeth of Vermandois, or Elisabeth or Isabel de Vermandois (c. 1085 – 1131), was the third daughter of Hugh Magnus and Adelaide of Vermandois,[1] and as such represented both the Capetian line of her paternal grandfather Henry I of France, and the Carolingian ancestry of her maternal grandfather Herbert IV of Vermandois.[2] As the wife of two Anglo-Norman magnates, Robert de Beaumont, 1st Earl of Leicester and William de Warenne, 2nd Earl of Surrey, she is the ancestress of hundreds of well-known families down to the present time.[3] She is the ancestress of all Scottish rulers including and after her grandson Malcolm IV and all English rulers starting with Henry IV
