1. MARINO (-[Aug/Sep] 824). The primary source which confirms his parentage has not yet been identified. Count of Brescia. He succeeded in [Aug] 824 as MARINO Duke of Spoleto. "Mauring Count of Brescia" was elected to succeed Adalhard as Duke of Spoleto, but died "within a few days"[897]. Einhard's Annales record the appointment of "Moringus Brixiæ comes" as Duke of Spoleto after the death of "Adalhardus" but that he died within a few days[898]. Neither of these sources specify the relationship between Mauring and Duke Suppo I.
