The Genealogiæ Scriptoris Fusniacensis refers to a sister of "comes Rainaldus" as husband of "Gillebertus, filius Richardi Anglici". Guillaume of Jumièges records that “Giselbertus” married “filia comitis de Claromonte”. "Hadalaidis filia Hugonis de Claromonte…uxor Gisleberti de Anglia" founded an anniversary at Saint-Leu d’Esserent, like the anniversaries of "patris sui Hugonis et matris sue Margarite", by undated charter.

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”, 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. 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. [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. 2
