MATHILDE de Vermandois.

The Chronicle of Alberic de Trois-Fontaines records the proposed marriage of "Robertus comes Mellentinus" and the daughter of "Hugonis Crispeiensis comes" which was prohibited by "Yvo [episcopus]" on grounds of consanguinity, the mutual descent of the two parties from "Gauterus Albus de Albamarla" being set out in the chronicle although the name of the daughter is not given[1338]. It is not known to which daughter this refers, but it may be Mathilde.

The Genealogiæ Scriptoris Fusniacensis refers to (but does not name) the second of the daughters of "Hugonem Magnum [et] Adelaide comitissa Veromandensium" as wife of "Radulfo de Baugenci", parents of "Simonem eiusdem loci principem"[1339]. "Domnus Radulfus de Balgentiaco" donated a wood to La Trinité de Vendôme, with a reserve for "uxor eius domna Mathildis", by charter dated 1105[1340].

She is named in the testament of "Simon Balgenciacensis dominus" dated to [1146/53] which names "Radulfi mei patris et Matildis mei matris"[1341].

The fact that Mathilde was the eldest daughter is confirmed by the De Genere Comitum Flandrensium, Notæ Parisienses which records "Agnes uxor domini Ingelranni de Cociaco" as daughter of "domina de Baugenciaco primogenita [comitis Hugonis li Maines]"[1342].
