- Born: Between 805 and 810, Friuli, Italy
- Married: Abt 836

His origin is stated in the poem by Sedulius addressed to "Everhardum comitem…Hunroci proles". His birth date is estimated on the basis of his marriage in . Thegan's Vita Hludowici Imperatoris names "Walach…abbas et Rihhardus perfidus et Eberhardus fidelis" as legates of Lothar, son of Emperor Louis I, in Italy in May .
Eberhard stopped the invasion of the Slavs and received the March of Friulia from Emperor Lothaire I, becoming EBERHARD Duke of the March of Friulia. The Chronicle of Alberic de Trois-Fontaines records that "comes Everardus cognomento Radulfus" was made "dux Foroiulii" by Emperor Lothaire. An agreement between Charles II "le Chauve" King of the West Franks and his brother Ludwig II "der Deutsche" King of the East Franks dated Jun 860 names "nobilis ac fidelibus laicis…Chuonradus, Evrardus, Adalardus, Arnustus, Warnarius, Liutfridus, Hruodolfus, Erkingarius, Gislebertus, Ratbodus, Arnulfus, Hugo, item Chuonradus, Liutharius, Berengarius, Matfridus, Boso, Sigeri, Hartmannus, Liuthardus, Richuinus, Wigricus, Hunfridus, Bernoldus, Hatto, Adalbertus, Burchardus, Christianus, Leutulfus, Hessi, Herimannus, item Hruodulfus, Sigehardus". The Annales Alamannicorum record "Eberhart" among those who swore allegiance in 864. With his wife, he founded the abbey of St Calixtus at Cysoing, Flanders.
The Annales Xantenses record the death in 866 of "Everwinus gener Ludewici regis" in Italy. Assuming that this refers to Eberhard, it is surprising that the text refers to "Ludewici regis" rather than "Ludewici imperatoris". Eberhard's father-in-law is not known to have used the title king after his imperial coronation, although in a previous part of the same text the Annales refer to his mother-in-law as "Iuthit regina". It is improbable that the Annales could refer to Louis "le Jeune" King of Italy (who was reigning in 866 and died in 875) as his daughters were probably under marriageable age at the time and in any case no other reference has been found to one of them marrying "Everwinus". The Historia Ecclesiæ Cisoniensis records the testament of “Evrardus comes cum coniuge mea Gisla”, dated “Hludovico Augusto anno regni eius XXIV” and witnessed by “Adalroch nepos noster”, which bequeathes property “in Langobardia et in Alamannia” to “primogenitus…noster Unroch”, property “cortem in Anaspio…præter Grecinam et cortem nostrum Hildiolam in Hasbannis…et…in pago Condustrim” to “secundus…Berengarius”, property “in Cisonio et Cansinium” to “tertius Adalardus”, property “Vitrei…Mesrucha…in Cisonio…et…in Sceleburd…quod Matridus…habuit” to “quartus Rodulfus”, and to “filiabus…nostris…Ingeldrud…Ermen et Mareshem, Judith…[in] Balgingam et cortem nostrum in pago Moila…Helisheim…Heilvinch…Hattrenheim et Luisinga et Wendesse et unum manum in Engerestheim”, and also lists a large number of books. 1
Eberhard married Gisela CAROLING, daughter of Louis I "Le Pieux" CAROLING Holy Roman Emperor and Judith VON ALTDORF, about 836.
