Alix (Adela) de Valois

NOTE: she is not the same as Adelais de Valois who married Heribert IV Comte de Vermandois.

Although some sources place Alix de Valois (de Crepi) as the daughter of Raoul II and Alix de Breteuil, evidence provided by the FMG Medieval Lands database indicates that she was a sister of Simon and therefore would be the daughter of Raoul III Comte de Valois & du Vexin and Aelis de Bar-sur-Aube:

daughters of RAOUL [III] “le Grand” Comte de Valois d'Amiens et du Vexin and his wife Adele de Bar-sur-Aube included:

SUBJECT OF THIS PROFILE: ADELA [Alix] de Valois (-12 May [1093/1100], bur Saint-Faron). It is unclear whether the [second/third] wife of Thibaut III Comte de Blois could have been the daughter of Comte Raoul [III]. The Chronicle of Alberic de Trois-Fontaines names "Alaydis soror sancti Symonis" as wife of "comiti Campanie Theobaldo", although he confuses her with her supposed niece Adelais, daughter of Héribert [IV] Comte de Vermandois, saying that she married "Hugoni fratri regis Philippi" after the death of her husband[39]. The difficulty with Alberic’s statement is an undated charter, quoted by Acta Sanctorum, under which "Rodulfus comes" donated property to Saint-Rémy, confirmed by "Symonem filium meum, duos quoque generos meos, quos de filiabus meis habeo, id est Heribertum comitem et juvenem…Bartholomeum"[40]. If the wife of Comte Thibaut III had been another daughter of Raoul [III], it is unclear why he would have been omitted from this document which appears to indicate clearly that Raoul had only two sons-in-law. Nevertheless, a close relationship with the family of the comtes de Valois is indicated by a charter dated to [1077/81] under which "Teobaudus comes palatinus…cum mulierum Adelaide" donated property to Montiérender, naming "bone memorie predecessorum…patris sui Odonis comitis et Heriberto cognomento senioris…comes Rodulfus predecessor suus et propinquus"[41], the latter presumably referring to Comte Raoul [III]. In addition, Comte Thibaut acquired the county of Bar-sur-Aube. If he had not been Raoul’s son-in-law, the basis for this acquisition is unclear. "Adeladis comitisse" subscribed the donation to Cluny by "Rotrocus castri Mauritanie comes atque Dunensis castri vicecomes" dated 11 Jan 1078, immediately after "Tetbaldi comitis, Stephani comitis"[42], it being assumed that she was the wife of the former not the latter. The necrology of Saint-Loup, Troyes records the death "XII Mai" of "Aalais uxor Theobaudi comitis Campaniæ" and her burial "in monasterio Sancti Faronis"[43]. m (before 1061) as his [second/third] wife, THIBAUT III Comte de Blois, Chartres et Champagne, son of EUDES II Comte de Blois, Chartres, Troyes et Champagne & his second wife Ermengarde d'Auvergne ([1010]-29/30 Sep 1089).]

Do NOT confuse her with her sister who married Herbert de Vermandois: ADELAIS de Valois (-after 1077). The Chronicle of Alberic de Trois-Fontaines names "Symonem et filiam…Adala" as children of "comitis Veromandie [error for Valois] Rodolfi" and his wife Adela[36]. Her marriage is confirmed by an undated charter, quoted by Acta Sanctorum, under which "Rodulfus comes" donated property to Saint-Rémy, confirmed by "Symonem filium meum, duos quoque generos meos, quos de filiabus meis habeo, id est Heribertum comitem et juvenem…Bartholomeum"[37]. Ctss de Valois. "Herbertus Vermandensium et Vadascorum comes" donated property to the church of Saint-Quentin and others, with the consent of "Alide coniugis meæ", by charter dated 1059 (date unlikely to be correct, considering that Héribert did not succeed as Comte de Valois until 1077)[38]. m ([1059 or before]) HERIBERT [VI] Comte de Vermandois, son of EUDES Comte de Vermandois & his wife Pavia --- ([1032]-[1080])
