EUDES ([770/80]-killed in battle [Touraine] Jun 834). His birth date is estimated on the assumption that he was already mature when named for the first time in 810/11, but bearing in mind his active participation in the 834 battle in which he was killed. The Annales Fuldenses record that "Odo legatus imperatoris…orientalium Saxonum præsidium" was captured by "Wilzis" in 810[125]. Einhard's Annales record "Uodo comes" as one of the signatories of peace with the Vikings in 811[126]. He became Comte d'Orléans after the territory was forfeited by Matfried[127]: the Miracula Sancti Bernardi records that "Matfrido, comite quondam Aurelianensi" was deprived of his honours "culpam inertiæ" and "Odo" appointed in his place[128], presumably dated to [828]. From that time, Eudes and his brother Guillaume were the most powerful supporters of Emperor Louis "le Pieux" against his son Lothaire, whose rebellion was supported by Matfried. The Vita Hludowici Imperatoris records that "Aurelianensem urbem" was taken from "Hodone" and restored to "Mathfrido" [in 830][129]. The Annales Bertiniani record that "Odo et Willelmus frater eius" were among those killed fighting "Lantbertum et Matfridem" in 834[130]. Merlet suggests that the battle took place in Touraine[131]. The Annales Xantenses record that "Uodo comes et Theodo abbas" were killed in 834[132]. The Annales Fuldenses record the rebellion of "Mahtfredo et Lantberto" in 834 and the battle in which "Udo comes Aurelianensium et Theodo abbas sancti Martini Turonensis" were killed[133]. The Chronicle of Adémar de Chabannes records that "Odo Aurelianorum comes"was killed fighting "Lamberto Nannetensi comite"[134]. The Miracula Sancti Bernardi names "Odonem fratremque illius Guillelmum, comitem Blesensium, Teutonem denique abbatem Sancti Martini, Guidonem comitem Cenomanensem" among those killed in battle against Lambert Comte de Nantes[135]. The Chronica Rainaldi records that "Odo comes Aurelianensium, Willelmus frater eius comes Blesensium, Guido comes Cenomanensium" died in battle fighting "Lambertum" in 835[136]. It is more likely that this battle took place in 834, assuming that it is correct that Count Lantbert was established in Italy later that year. [m firstly ---. The charter quoted below, which records the confirmation of a donation to Tours Saint-Martin made by Comte Eudes and his son Guillaume, suggests that Guillaume must have been considerably older than his sister Ermentrudis (whose birth is estimated to [830], see below). If this is correct, it is possible that Guillaume was born from an earlier marriage of his father. The possibility of such an earlier marriage is also indicated by Eudes’s estimated birth date as shown above.] m [secondly] ENGELTRUDIS, sister of ADALHARD [IV], daughter of [LIUTHARD Comte de Fézensac & his wife Grimhild ---]. The wife of Eudes is named by Nithard who records "Hirmentrude, daughter of Odo and Ingiltrud" as the wife of Charles[137]. The primary source which establishes that she was the daughter of Adalhard [III] has not yet been identified. However, the Annales Bertiniani suggest that she was the sister of Adalhard [IV] when they record that "Carlomannus, Hlodowici regis Germaniæ" sought refuge with "Adalardo, Yrmintrudis reginæ avunculo, suo autem propinquo" after he was banished by his father following his rebellion in 861[138].
[Three] siblings, parents not known. The poem by Gosbert, addressed to the brother "Guillelmum Blesensium comitem", which refers to him as "Francigenum primo proavis abavisque peralto"[122] suggests that their ancestry was illustrious. Levillain identifies Eudes with Odo, son of [Adrianus [Udalrichinger] & his wife Waldrada ---][123]. This seems unlikely to be correct as the name Guillaume/Wilhelm (brother of Eudes Comte d’Orléans) does not appear at all in the Udalrichinger family, although it is possible that the name could have been introduced from their mother’s family. A possible clue about the origins of Eudes's mother is provided by the Vita Hludowici Imperatoris which records the blinding of "Heribertus Bernhardi frater" and his exile with "Hodo consobrinus illius"[124]. The previous passage in the Vita records the confiscation of Orléans from Eudes Comte d'Orléans. It is possible that he was the same person as "Hodo", although if this is correct the precise nature of the relationship between him and Héribert has not been established. Assuming that Héribert was the son of Guillaume de Toulouse and his first wife Cunigundis (about which there is some doubt, as explained elsewhere in this document), and assuming also that "consobrinus" is used in the text in its strict sense, Cunegundis and the mother of Eudes Comte d'Orléans would have been sisters.
