Weis' "Ancestral Roots . . ." (146:15), (191:16), (250:15). In his book, "Early Medieval Italy", Chris Wickham, refers to him as an Italo-Frankish magnate who held lands stretching from Belgium to Veneto (the province of Italy in which the city of Friole is located). When he divided these lands between his heirs in 864, he explicitly instructed them to redivide them if civil wars between the adherents of the Emperor, LOUIS THE PIOUS and his son, the future Emperor, LOTHAR I, caused the loss of any of them. (These two Emperors were Everard's father-in-law and brother-in-law.) LOTHAR's son and heir as king of Italy, LOUIS II continued to rely upon Everard and the other great magnates of his father's reign in his administration of the kingdom of Italy.
Everard owned what was, in his time, considered to be a very extensive library of over 50 books and was considered exceptional that he was one of the few men of his day who was literate enough to be able to read Virgil for pleasure.
