Her name [Widinildis] as wife of Raymond and Countess of Toulouse is provided by the charter dated 28 Sep 926, under which "Teudericus et uxor mea…Sposia" donated property to Narbonne cathedral, signed by "Vulveradus vicecomes…Widinildis comitissa, Richildis vicecomitissa…"[232]. As Narbonne was under the suzerainty of the comtes de Toulouse, it is possible that "Widinildis comitissa" was the legal representative of the county at the time, widow of the former comte and acting in the capacity of guardian for her minor son. According to Europäische Stammtafeln[233], she was [Guinidilda] [de Barcelona, daughter of Guifré [I] "el Velloso/el Pilós/the Hairy" Conde de Barcelona & his wife Guinidilda ---]. As Guinidilda was also the name of the wife of Conde Guifré I, a connection seems likely, although it is also possible that "Vuidinildis comitissa" belonged to the same family as Guinidilda senior (about whose family nothing is known either). Comte Raymond II & his wife had one child:

a) RAYMOND ([900/10]-[944/69], bur Saint-Pons-de-Thomières). His parentage is confirmed by the charter under which "Pontius…comes Tolosanus, primarchio et dux Aquitanorum et uxor mea Garsindis" donated property to the abbey of Saint-Pons de Thomières, for the souls of "genitore nostro Raimundo et genetrice mea"[234]. He succeeded his father in [923/24] as RAYMOND PONS Comte de Toulouse.
