BAUDOUIN, son of [ODACRE [Audacer or Odoscer] & his wife ---] ([830/37]-Arras 879, bur Abbaye de Saint-Bertin near Saint-Omer[36]). The Genealogia Comitum Flandriæ Bertiniana, dated to the second decade of the 12th century, names "Balduinum Ferreum" as son of "Audacer"[37]. The Genealogia Comitum Flandriæ names "Balduinum Ferreum" as son of "Audacer"[38]. He is named as son of Audacer in the list of counts of Flanders recorded in the Cartulaire de Saint-Bertin, which records his year of death and place of burial[39]. His birth date range is estimated on the assumption that he was a young adult at the time of his marriage, which means that he must have been a child when his father died. He eloped with his future wife around Christmas 861. The Annales Blandinienses name "Baldwinum Ferreum filium Audacri" and "Balduvinus filius Audacri" when recording (respectively) his elopement with his wife in 862 and his death in 879[40]. He was granted the "pagus Flandrensis" in 863, and shortly after Ternois, Waas and the lay abbacy of St Peter of Gent[41], although the primary sources on which this is based have not yet been identified. He is known to history as BAUDOUIN I "der Gute/Ferreus/der Eisenarme" Count of Flanders, but it is improbable that he was referred to as such by contemporaries. An agreement dated 14 Jun 877 of Emperor Charles II "le Chauve", presumably written with his own death in mind, names "…ex comitibus aut Tedericus, aut Balduinus, sive Chuonradus, seu Adalelmus" as those willing to support the emperor's son[42]. The Annales Blandinienses record the death in 879 of "Balduvinus, filius Audacri", specifying that he was buried at "Blandinie"[43]. According to legend, he built the church of St Donatien ("Sint Donaatskapittel") at Bruges.
m (Auxerre 13 Dec 862) as her third husband, JUDITH, widow firstly of ÆTHELWULF King of Wessex and secondly of ÆTHELBALD King of Wessex, daughter of CHARLES II "le Chauve" King of the West Franks [Carolingian] & his first wife Ermentrude [d'Orléans] ([844]-after [870]). She is named as wife of Baudouin in the list of counts of Flanders recorded in the Cartulaire de Saint-Bertin, which also names her parents and her three sons[44]. She and her father are named by Roger of Hoveden when he records her marriage to King Æthelwulf[45]. Asser records that "Iuthittam, Karoli Francorum regis filiam" married "Æthelbald filius eius [=Æthelwulfo rege]" after the death of her first husband, commenting that it was "cum magna ab omnibus audientibus infamia"[46]. Roger of Hoveden also records this second marriage of Judith[47]. Flodoard names "Balduini comitis et Iudita…Karoli regis filia, Edilvulfo regi Anglorum qui et Edelboldus in matrimonium"[48]. The Genealogica Arnulfi Comitis names (in order) "Iudith et Hildegardim, Hirmintrudim et Gislam" as the four daughters of "Karolus imperator…ex Hyrmentrudi regina", specifying that Judith married "Balduinus comes"[49]. The Annales Bertiniani record that Judith returned to her father after the death of her second husband, lived at Senlis "sub tuitione paterna", and from there was abducted by "Balduinum comitem" with the consent of her brother Louis, her father consenting to the marriage the following year[50]. The Annales Elnonenses Minores record the marriage in 862 of "Balduinus, Odacri filius" and "Iudith, Caroli regis filiam"[51]. The preceding information is pulled together by the Genealogia Comitum Flandriæ which names "Iudith vidua Adelbaldi regis Anglorum, filia Karoli Calvi regis Francorum" as the wife of "Balduinum Ferreum"[52]. No information has been found in the primary sources so far consulted which throws light on the possible date of death of Judith, although it is unlikely that she died before about 870 at the earliest assuming that she was the mother of all the children referred to below.
