|Agnès DE MONTFAUCON, Comtesse de Brienne
(Abt 1153-Aft 1186)
Agnès DE MONTFAUCON, Comtesse de Brienne
- Born: Between 1150 and 1155, Montbéliard, Doubs, Franche-Comte, France
- Married: Before 1166
- Died: 23 October, after 1186
Also called Agnès DE MONTBÉLIARD.
Her parentage is indicated by William of Tyre (Continuator), who names "le conte Gautier de Briene qui fu fiz dou conte Erart de Brienne et de la fille dou conte Ami de Monbliart" and says that “Rechart le conte de Monbliart et Gautier son frere furent ses oncles de par sa mere”. If that is correct, the chronology of her husband’s family suggests that Agnes was much older than her brothers. "Agnetis uxoris mee" consented to the donation by "Erardus Brenensis comes" recorded in the latter's charter dated 1166. The date of this charter suggests that Agnes must have been one of her parents’s older children to have been married before that time. Her birth date range is estimated from the birth of her fourth son which is estimated to [1170/75]. This in turn suggests that she was not born from the same marriage as her brother Richard [III]. "Erardus Brenensium comes…Agnetis uxoris mee et Galterii filii mei" donated property to Basse-Fontaine by charter dated 1185. "Erardus Brenensium comes" donated property to Basse-Fontaine with the consent of "Agnetis uxoris mee et Galteri et Guillelmi filiorum meorum" by charter dated 1186.
The necrology of Chartres cathedral records the death "X Kal Nov" of "Agnes…comitissa de Breina". 1
Agnès married Cte Erard II DE BRIENNE, son of Cte Gauthier II DE BRIENNE and Humberline DE BAUDÉMENT, before 1166. (Erard II DE BRIENNE died on 8 Feb 1190/1.)
