"…Matildis soror mea…" consented to the donation by "Radulfus…comes Clarimontis" to the abbey of Notre-Dame d'Ourscamp by charter dated 1162. The primary source which confirms the identity of Mathilde's mother has not been identified. As noted above, the fact that Mathilde and her brothers Simon and Etienne subscribed the 1162 charter, without any of their other named [half-]brothers, suggests that the two groups of brothers and sisters may have been born from different marriages, although the issue is not without doubt. Mathilde was probably heiress of Dammartin, inherited from her mother. At first sight this would suggest that she may have been born from her mother’s first marriage, except that her donation made in 1218 suggests the improbability of her birth before . Louvet notes a donation to the priory of Gournay-sur-Aronde made by “Rainal Comte de Clermont et Clemence sa femme” which was confirmed and supplemented in 1165 by “leurs enfans...Raoult Comte de Clermont, Simon, Gautier, Margueritte, Matilde et Comtesse”. "R…comes Clarimontis et dominus Brituliensis…et Aeliz comitissam uxorem meam" confirmed the donation to the church of Breteuil by "Sangalo de Garda Malgerii, Henricus filius eius" by undated charter, witnessed by "Albericus Domni Martini comes et Mahaux soror mea, Domni Martini comitissa, Rainaldus castellanus Britulii…". "Albericus comes Domni Martini et Raynaldus filius meus comes Boloniæ et Matildis uxor mea comitissa" donated property to Dammartin Saint-Pierre by charter dated 1185. King Philippe II confirmed the donation made by “Mathilde jadis comtesse de Dammartin” to the nuns of Parc near Crespi of revenue from “la prévôté de Crespi”, which the king had previously granted to her in return for her rights over the county of Clermont after the death of [her great-nephew] Thibaud VI Comte de Blois, by charter dated [May/Jul] 1218. 1
Mathilda married Cte Aubrey II DE DAMMARTIN, seigneur de la Ferté-Alais et de Lillebonne, son of Aubri I DE MELLO, administrateur du comté de Dammartin and Clémence DE BEAUVAIS, after 1162. (Aubrey II DE DAMMARTIN died on 20 Sep 1200 in Lillebonne, Seine-Maritime, Haute-Normandie, France.)
