His parentage is confirmed by the charter dated 3 Nov 862 under which "Raymundus…comes et marchio et uxor mea Berteyz" founded the abbey of Vabres, naming "Bernardum filium nostrum…Fulgualdus filius noster…Odo filius noster" (all three of whom also subscribed the document).
He succeeded as ODON Comte de Toulouse. "Bertheiz sagaci" donated property to Vabres, for the souls of "genitoris mei Remigii hac genetricis meæ Arsinda" and for "iugale meo Raimundo et filio meo Bernardo qui fuerunt quondam, seu et filio meo Odone et Benedicto", by charter dated 6 Apr 883. "Oddo…comes uxorque mea Garsindis" exchanged property with Frotaire Archbishop of Bourges by charter dated to [886] witnessed by "Airberti fratris eius, Garsiæ scriptoris comitis, Willelmi comitis…". "Oddo…comes uxorque mea Garsindis" sold property "in comitatu Lemovicino…villa…Orbaciacus" by charter dated Aug 887, with the consent of "fratre nostro Airberto" and subscribed by "Garsis comitis, Willelmi comitis…". The charter dated 16 Jun 918, which records an audience at Ausonne in the diocesis of Carcassonnne held by "Aridemandus episcopus sedis Tolosæ civitatis...missus advocatus Raymundo comite Tolosæ civitatis et marchio" with the consent of "Odone comite genitore suo", suggests that Odon resigned the county in favour of his son Raymond before he died. 2
