from http://www3.sympatico.ca/robert.sewell/capet.html#gen13: Isabel married in 1096 to Robert de Beaumont (born circa 1049 and died on June 5, 1118), Lord of Beaumont, Post-Audemer Brionne and Vatteville; Count of Meulan; created 1st Earl of Leicester. Robert de Beaumont was present at the Battle of Hastings. He was a son of Roger, Seigneur de Beaumont and Adeline, a daughter of Waleran, Count of Meulan.
Isabel and Robert had children which tend to be confusing because Waleran and Robert were twins born in 1104. Both married ladies names "de Montfort" and both had sons named Sir Robert de Beaumont. One begins to wonder if perhaps Robert and Waleran were the same person, but there are differences as shown next.
Isabel's and Robert's children were: Waleran de Beaumont (1104 - 1166, twin brother of Robert de Beaumont), Count of Meulan and Earl of Worcester who married circa 1141 to Agnes de Montfort,a daughter of Amauri de Montfort, Count of Évreux. They had a son:
