Flaccovio, absolutely rare, would seem to be specific to Palermo, the surname whose history cannot be identified, could be of Norman origin and derive from an Italianization of the Norman name Flahauw, which should have originated from an alteration of the Germanic medieval name Fladwulf, in turn composed of the terms flat (purity) and wulf (wolf), with the meaning of pure-bred Wolf, it must be remembered that the wolf among the Nordic peoples represented strength, courage and family, one cannot exclude but that it may be a fancy surname attributed to a foundling.
