JEAN (-before 1290, bur Saint-André de Gouffern). "Haymericus vicecomes Castri Eraudi" donated property to Saint-Denis en Vaux by charter dated 1240 which names "nobilis mulier Agatha uxor eiusdem Haymerici vicecomitis et Johannes filius eorumdem"[590]. Sire de Sonnois et de Montgommery. "Johannes vicecomes de Castriheraudi et dominus Sagonensis" donated revenue from Peray to Perseigne abbey, confirming the donation made by "bone memorie Roberti quondam comitis Alentionis avunculi patris mei", by charter dated Apr 1263[591]. m MATHILDE de Dammartin, daughter of SIMON de Dammartin Comte d'Aumâle et de Ponthieu & his wife Marie de Ponthieu (before [1220]-after Jan 1257). The Chronicle of Alberic de Trois-Fontaines refers to, but does not name, the four daughters of "comes de Pontivo Symon" (in order) as the wives of "rex Castelle de Hispanie Fernandus…filius vicecomitis de Castro Araudi…filius comitis de Augo…comes de Roceio"[592]. The wording of this passage means that the husband of this Dammartin daughter was not Aimery [II] Vicomte de Châtellerault, as shown in many secondary sources, which would in any case be chronologically impossible, but his son[593]. In addition, the full passage appears to indicate that the wife of "filius vicecomitis de Castro Airaudi" was the oldest of the four daughters as she is referred to "alteram natu maiorem", even though her husband is mentioned second in the list. This would seem surprising considering that the county of Ponthieu was inherited by Jeanne, wife of Fernando III King of Castile. The charter dated Aug 1237, quoted in full in the document NORTHERN FRANCE, under which her parents name their daughter Jeanne "primogenite nostre J. …regine Yspanie et Castelle", confirms that Jeanne was indeed the oldest daughter[594]. One possible explanation of Alberic´s text is that he intended to indicate that the daughter whose husband was named second in his list was the oldest of the remaining daughters, although such a reference would seem superfluous. Interestingly, Butkens states, in his commentary relating to the Dammartin-Ponthieu family, that (1) this daughter married "le fils du Vicomte de Chastellerault" and (2) that she was the oldest daughter[595], the latter statement presumably being based on a literal interpretation of the passage in Alberic which, as explained above, is contradicted by the charter dated Aug 1237. Butkens, in the same passage, says that "le fils du Vicomte de Chastellerault…n´en eust pas de lignée" (from his wife, Simon´s daughter), although as shown below this statement is incorrect. The wife of Vicomte Jean was named Mathilde, as shown by the charter dated Jan 1256 under which "Matildis nostra uxor" confirmed a donation to the abbey of Bécheron by "Johannes vicecomes Castri Ayraudi"[596]. Mathilde was presumably named after her paternal grandmother. The charter dated 1291, under which "Jean de Harcourt chevalier et Jeanne vicomtesse de Châtellerault sa femme, fille de Jean vicomte de Châtellerault" confirmed all the donations to Saint-André-en-Gouffern made by their predecessors[597], indicates that Mathilde was the mother of Jean´s daughter Jeanne, as other donations to Saint-André-en-Gouffern which are recorded in the same source were made by the comtes de Ponthieu (ancestors of Mathilde), not by the vicomtes de Châtellerault. If it is correct that Mathilde was the second daughter of Simon de Dammartin and his wife, it is likely that she was married after her sister Jeanne, whose marriage can be dated to before Aug 1237. Jean & his wife had one child:
