PIERRE [IV] [de Chambly] (-after [Apr 1228]). Depoin refers to “une mention nécrologique” (no citation) relating to a donation made by “Herbert doyen de Senlis” which names his parents “Pierre Hideux et Gila” and his brother “Pierre Hideux le Jeune”[187]. As noted above, it appears more likely from a chronological point of view that this document refers to the sons of Pierre [III]. A manuscript list of feeholders in the county of Beaumont-sur-Oise during the reign of King Philippe II includes “Petrus Hideus...Petrus Hideus de Chambli” and the statement that “Petrus Hideus” was “homoligius de feodo Baldoini de Bellovidere”[188].

He suggests that it was Pierre [III] who was “homoligius de feodo Baldoini de Bellovidere”, which appears to be corroborated by the charter dated Oct 1275 under which King Philippe III repurchased from “Petrus de Chambeliaco…cambellanus…noster” various revenues from Beaumont and Méru, including the right to revenue bought by “defunctus Petrus quondam avus suus” from “Baldoino de Bellovidere”[191]. This hypothesis assumes that “Petrus de Chambeliaco…cambellanus…noster” in that document was Pierre [V]. If on the other hand it was Pierre [VI], it would be Pierre [IV] who was “homoligius de feodo Baldoini de Bellovidere”.
