Isabel was also known as Avice and Hawise.
An anonymous continuation of the Chronicle of Robert of Mont-Saint-Michel records (in order) "Comitissa Ebroicensis…uxor Guillelmi Comitis de Clara, tertia…in manu Dei et domini Regis" as the three daughters left by "Guillelmus Comes Glocestriæ" when he died. The Chronica de Fundatoribus et Fundatione of Tewkesbury Abbey names “Mabiliam comiti de Evereis in Normannia nuptam…Amiciam…Isabellam” as the three daughters of “comes Willielmus” and his wife, adding that Isabel married “Henricus rex…Johanni filio suo”. Benedict of Peterborough records the betrothal in 1176 of "Johannem filium regis minimum" and "Willelmus filius Roberti filii regis Henrici primi comes Gloucestriæ…filiam ipsius comitis" and the agreement whereby John would inherit the county of Gloucester. Her marriage is recorded by Matthew Paris, who specifies that it took place despite the prohibition of Baldwin Archbishop of Canterbury on the grounds of consanguinity, although he does not name her. The Chronicle of Ralph of Coggeshall records that "comes Johannes frater eius [rege Ricardo]" married "filiam comitis Glocestriæ".
She was recognised as Ctss of Gloucester in her own right from her marriage in . Matthew Paris records that the king divorced "uxorem suam Hawisam comitis Gloverniæ filiæ" [in 1200 from the context] because “affines erant in tertio gradu consanguinitatis”. The Annales Londonienses record the divorce in 1200 of King John and "Hawysiam filiam comitis Gloverniæ", stating that they were "in tertio gradu consanguinitatis". King John appears to have kept her as a state prisoner after their divorce, but retained her title even after her nephew Amaury de Montfort was installed as Earl of Gloucester in 1199.
The Chronica de Fundatoribus et Fundatione of Tewkesbury Abbey records the second marriage of “Isabellam” and “Galfrido de Mandevile comiti Essexiæ”, and her third marriage to “Huberto de Burgo justiciario Angliæ”. Her lands and title were confiscated on the death of her second husband.
The Annals of Waverley record the death in 1217 of “Isabel comitissa Gloucestriæ”. The Annals of Dunstable record that “Johannam comitissam Gloucestriæ” died “paucos dies” after her marriage to “Hubertus de Burgo justiciarius Angliæ” and was buried “apud Cantuarium”. 1
