BOUCHARD [III] de Montmorency, son of HERVE Seigneur de Montmorency & his wife Agnes --- (-Jerusalem [2 Jan], after 1124). "Herveus de Marleio et uxor mea Agnes, Burcardus…filius meus" donated the church of Marly to the abbey of Notre-Dame de Colombs en Beausse by charter dated 1087[571]. Seigneur de Montmorency, de Marly, de Feuillarde, de Saint-Brice, d'Epinay et d'Hérouville. The Liber translationis et miraculorum B. Honorinærecords that “domino de Montmorenceio Burcardo” burned the church of Conflans during his war with “comiti Matheo de Bellomonte”, dated to 21 Jun 1086[572]. "Burchardus de Montemaurinciaco" confirmed donations made to Saint-Martin des Champs, Paris by "miles…Paganus…a baptismate Walterius et uxor eius a baptismate Hodierna Comitissa nuncupata" by charter dated 1096, witnessed by “milites eius...Hugo filius Theoderici, Odo filius Odonis, Hugo de Warenna, Richardus filius Theoderici...”[573]. Suger's Vita Ludovici records a dispute between the abbot of Saint-Denis and "Burchardum...dominum Monmorenciacensem" during the course of which the future Louis VI King of France, together with "Matthæum Bellimontensem comitem et Drogonem Monciacensem", invaded “terram eiusdem Burchardi”, dated to [1101][574]. "Dnus Bucardus de Monte Morentiaco" donated road tolls at Saint-Denis to the abbey of Saint-Martin de Pontoise for the souls of "uxorisque suæ, filiorum filiarumque suarum" with the consent of "filium suum Mathæum" by charter dated [1102][575]. "Bocardus Munmorenci castelli dominus" donated property to Chartres Saint-Père, in the presence of "Matheo comite Belli Montis", by charter dated to before 1112, later confirmed by "Matheus filius Bocardi"[576]. An undated charter records a donation to Chantilly made by "Herveus de Montmaurenciaco", and the later confirmation by "dominus Burchardus supradicti Hervei filius…fratrum eius Hervei clerici, Theobaldi de Marli et Mathei" for the souls of "uxorum suarum et filiorum suorum"[577]. Orderic Vitalis records that "Burchardus de Monte Morencii, aliique prudentes" advised Louis VI King of France not to invade Normandy, dated to 1119, that "Mathæus comes de Bellomonte et Guido de Claromonte...ac Burchardus de Monte Morentii" led the invasion, that “Burchardum ac Otmundum et Albericum de Marolio“ were captured in battle at Brémule, and that “Burcardum ac Herveium de Gisortis...quia homines utriusque regis erant” were released by Henry I King of England[578]. The vassal relationship between Bouchard de Montmorency and King Henry has not been identified. A charter dated 1124 records an agreement between the prior of Saint-Martin-des-Champs and "Burchardum de Montemorenciaco" relating to earlier donations[579]. The necrology of the abbey of Notre-Dame du Val records on "XVI Kal Dec" that "Bucardus avus, Bucardus, Theobaldus de Montemorenciaco" died in Jerusalem[580], although it is not clear to which of the three deaths the date relates.
m firstly AGNES [de Beaumont] Dame de Conflans Sainte-Honorine, daughter of IVES [II] Comte de Beaumont-sur-Oise & his second wife Adelais ---. The primary source which confirms her parentage and marriage has not yet been identified. Duchesne cites no primary source which confirms the parentage of Bouchard [III]’s first wife but he highlights that Ives [II] Comte de Beaumont-sur-Oise founded the priory of Sainte-Honorine at Conflans, near Pontoise and that this property was later held by Bouchard [III] Seigneur de Montmorency[581]. The necrology of the priory of Beaumont-sur-Oise records the death "Id Jul" of "Hugo frater Methei comitis, Agnes soror eius"[582].
m secondly (before 1105) AGNES, daughter of RAOUL Deliés [Seigneur de Pontoise] & his wife Hazecha [Hawise] --- (-[18 Jul] ----). "Radulfus Delicatus et Hahuis loco Agnetis filiæ suæ" confirmed donations made to Saint-Martin des Champs, Paris by "Lambertus nepos Humboldi concedente uxore sua Tesza" by undated charter[583]. "Radulfus Delicatus et uxor eius Hazecha" donated property to Saint-Martin des Champs, Paris, with the consent of "eorum filiis Radulfo et Amalrico atque filiabus Agnete et Cometissa", on the day that "uxor sua Hazecha" was buried in the church, by undated charter, witnessed by "Burchardus de Montemorentii…"[584]. "Burchardus de Montemorencii et Agnes uxor eius" confirmed donations to Saint-Martin des Champs, Paris made by "Radulfus Delicatus" by undated charter[585]. [The necrology of the abbaye du Val records the death "XV Kal Aug" of "Agnes de Montemorenciaco"[586]. It is probable that this entry refers to one of the wives of Bouchard [III].]
[m thirdly (after [1114/17]) as her second husband, ADELISA de Clermont, widow of GILBERT FitzRichard de Clare, daughter of HUGUES Comte de Clermont-en-Beauvaisis & his wife Marguerite de Ramerupt. The Genealogiæ Scriptoris Fusniacensis refers to a sister of "comes Rainaldus" as husband of "Gillebertus, filius Richardi Anglici"[587]. Guillaume of Jumièges records that “Giselbertus” married “filia comitis de Claromonte”[588]. Her second marriage into the Montmorency family is confirmed by the charter dated under which Robert Bishop of Lincoln confirms previous donations to Thorney, including one by “Adelidæ de Montemoraci” of “…terræ in Randa quas Turgisius tenuit et Toui prius dederat”[589], which clearly refers back to the earlier undated charter under which “Adeliz, uxor Gilberti filii Ricardi, et Gillebertus et Walterus et Baldewinus et Rohaisia pueri Gilberti” donated property “quod Tovi dedit…et in Randa…quas Turgisius tenebat” to Thorney Monastery[590]. The precise identity of Adelisa’s second husband has not yet been confirmed. According to Duchesne, Adelisa’s second husband was Hervé, son of Bouchard [III] Seigneur de Montmorency and his second wife, but he cites no primary source on which this statement is based[591]. As noted below, the first marriage of Mathieu [I] de Montmorency, who would have been Hervé’s older half-brother born from their father’s first marriage, is dated to [1126]. This suggests the birth of Mathieu [I] in [1095/1105]. If that estimated date range is correct, any half-brothers born from his father’s second marriage would probably have been too young to have married Adelisa. In addition, given Adelisa’s prominent family background and first marriage, it is unlikely that her second husband would have been the younger son of the seigneur de Montmorency. As Adelisa had several children by her first husband, she would have been considerably older than her second husband if he had been a younger son of Bouchard [III]. A more likely case is that Adelisa’s second husband was Bouchard [III] himself, whose age and position would have been more appropriate for the marriage. This is supported by the Liber Vitæ of Thorney abbey which lists "…Gilebt fili[us] Ricardi…Burchardus de Muntmorenci…Aaliz uxor Gilbti filii Ricardi…", suggested by Keats-Rohan as Adelisa and her two husbands[592].]
