HUGUES [I] de Châtillon, son of GAUCHER [III] Seigneur de Châtillon-sur-Marne Comte de Saint-Pol & his wife Elisabeth Ctss de Saint-Pol (- 9 Apr 1248). A charter dated 1219 records that "Galcherus quondam dictus comes Sancti Pauli" donated property to Saint-Denis, with the consent of "filiis suis Guidone et Hugone et uxore sua", by charter dated 1219[1811]. "Elisabeth de Castellione comitissa Sancti Pauli" confirmed an agreement between "Guidonem et Hugonem filios meos" and "Matheum de Rollepot militem" concerning "terra...Baulesche" by charter dated Jul 1220[1812]. "Hugo de Castellione, quondam filius Sancti Pauli comitis" founded the abbey of "Pons Beate Marie" by charter dated Apr 1226[1813]. He succeeded his father in 1219 as Seigneur de Châtillon, de Troissy, de Crècy et d'Ancre. He succeeded as Comte de Blois in 1231, by right of his second wife. "Hugo comes Sancti Pauli" did homage to Louis IX King of France for the lands of "mater mea I. comitissa Sancti Pauli et Johannes de Bethunia, qui dicebatur eius maritus" by charter dated [2/30] Apr 1233[1814]. He succeeded in 1240 as Comte de Saint-Pol. Matthew of Paris records the death at Avignon of "Hugo de Chastellone comes Sancti Pauli et de Bles" while crossing France on his way to join the Crusade[1815]. The necrology of Chartres cathedral records the death "V Id Apr" of "Hugo de Castellione comes Sancti Pauli", stating that "uxorem Mariam" donated property for his soul[1816]. "...Heredes comitis Sancti Pauli..." are named in the charter dated May 1249 which records payments made to the executors of the testament of "domini Philippi quondam comitis Bolonie"[1817].

m firstly (after Aug 1216) AGNES de Bar, daughter of THIBAUT I Comte de Bar & his second wife Ermesinde de Bar-sur-Seine (-before 1225). A marriage contract between "Galcherus de Castellione comes S. Pauli...filius meus Hugo" and "sorore...comitis Barriducis" is dated Aug 1216[1818]. The primary source which confirms her name has not yet been identified.

m secondly MARIE d'Avesnes, daughter of GAUTHIER [II] Seigneur d'Avesnes, Comte de Blois & his wife Marguerite Ctss de Blois (-after 12 Apr 1241). The late 13th century genealogy by Balduinus de Avennis names "unicam…filiam Mariam" as child of "dominus Galterus filius [Jacobi] primogeniti" and his wife, adding that she married "comiti Sancti-Pauli Hugoni"[1819]. She succeeded her mother in 1231 as Ctss de Blois. The testament of "Maria comitissa Blesis et Sancti Pauli" is dated 12 Apr 1241 and names "dominus meus Hugo de Castellione comes Sancti Pauli et Blesis et…matertera mea Ysabellis comitissa Carnotensis…Richardo de Bellomonte et…consanguinea mea Matildi uxore sua"[1820].

m thirdly MATHILDE de Guines, daughter of ARNOUL [II] Comte de Guines & his wife Beatrix de Bourbourg (-after 1262). The Historia Comitum Ghisnensium names "Beatricem, Christianam et Matildem" as the children of "castellana Broburgensis et Ardensis domina...Beatrix a viro suo...Arnoldo de Ghisnis"[1821]. The two sources quoted below suggest that her marriage is correct. However, the necrology of Chartres cathedral records the death "V Id Apr" of "Hugo de Castellione comes Sancti Pauli", stating that "uxorem Mariam" donated property for his soul[1822], "Mariam" presumably being a mistake in this entry for "Mathildem". Mathilde must have been middle-aged at the time of her marriage given the marriage date of her parents and the mention of her husband´s second wife in Apr 1241. Undated letters of "Mahaut de Ghisnes comtesse de S. Paul" acquitted "Jean de Chastillon comte de Blois fils aisné…messire Hue de Chastillon comte de S. Paul son mary" for her dower[1823]. A manuscript of Saint-Bertin records the death in 1262 of "Mathildis comitissa de Guisnes et S. Pauli vidua Hugonis de Sancto Paulo et Balduini comitis Guisnensis soror"[1824].

Comte Hugues & his second wife had four children
