CADELON [IV], son of CADELON [III] Vicomte d'Aulnay & his second wife Arsende --- ([970/85]-[1026] or after). "…Cadeleni vicecomitis, item Kadeleni filii sui, Radulfi fratris sui, item Cadeleni Sancti Maxentii" subscribed a charter dated [990/99] under which "Achardus filius Ebboni" donated property to St Cyprien[59]. "Cadelus" donated property to St Cyprien, Poitiers by charter dated [1010] subscribed by "Cadelonis filii eius, Hugonis iterum filii eius"[60]. Vicomte d'Aulnay. "…Cadilonis vicecomitis, Odolrici vicecomitis…" subscribed the charter dated 3 Aug 1016 under which "Guilelmus…dux Aquitaniensium" granted rights to Saint-Hilaire de Poitiers[61]. "Kadalonus vicecomes cum uxore mea Amelia et filio nostro Willelmo" donated property to Cluny by charter dated to [1020][62]. "Kadelonis vicecomitis…sive fratres…unus Radulphus alter quoque Constantinus et mater nostra Arsenda" donated property "in pago Alienense proper castrum super aqua Oriols" to Saint-Jean d'Angély by charter dated [1025][63]. "Kadelo vicecomes" donated property "in pago Alniense in vicario Santi Joannis" with the consent of "filio meo Vuillelmo necnon fratre meo Constantino atque sorore mee Ildiardi et filia mea Adelaidi" to Saint-Jean d'Angély by charter dated [1026][64]. "Engelbaldus Sancti Hilarii canonicus" donated property to St Cyprien by charter dated [1021/29] subscribed by "…Kadelonis vicecomitis…"[65]. [1026].
m AMELINE, daughter of ---. "Vuillelmus vicecomes" donated property "in pago Santonico in loco…Pinus" to Saint-Jean d'Angély by charter subscribed by "Amelinæ matris suæ, Constantini avunculi sui"[66]. This charter is dated to [1000] in the compilation, although there is no indication of the date in the text. If this supposed date is correct, "Vuillelmus vicecomes" must have been the son of Cadelon [V] by an otherwise unknown first wife Ameline. "Constantini avunculi sui" would then have been an otherwise unknown brother of Cadelon [V] or, if "avunculus" is given the strict sense, the brother of Ameline. The latter possibility is unlikely as the mother of Constantin, son of Cadelon [V], is recorded as Arsinde in another document (see above). It is therefore implausible that the name Constantin (unknown in earlier generations in the family) was introduced from his father's previous wife. The reconstruction on the basis of the [1000] date is therefore unsatisfactory. A more plausible explanation can be constructed if it assumed that the date [1000] is incorrect. This opens the possibility that "Vuillelmus vicecomes" was the son of Cadelon [VI], "Amelinæ matris suæ" the wife of Cadelon [VI], and "Constantini avunculi sui" was the brother of Cadelon [VI] who is recorded elsewhere. In addition, the document is subscribed, among others, by "Israel". This is also the name of the donor of property in a charter dated [1060/91] in the same compilation, which is consented to by "Vuillelmo vicecomite de Auniaco" who is presumably Guillaume son of Cadelon [VI] (see below)[67]. "Gelia famula Christi" donated property "in pago Santonico" to Saint-Jean d'Angély subscribed by "Kadelonis vicecomitis, Amelæ uxoris suæ, Vuillelmi vicecomitis, Arnaldi filii Eblonis", which also appears consistent with the hypothesis set out above concerning the identity of Ameline[68]. This last charter is dated to [1012] in the compilation but there is no indication in the text that this date is correct. Assuming that "Vuillelmi vicecomitis" is the son of Cadelon [VI], it is probable that the actual date of the charter is later. "Kadalonus vicecomes cum uxore mea Amelia et filio nostro Willelmo" donated property to Cluny by charter dated to [1020][69].
Cadelon [IV] & his wife had [four] children:
