Curiale has a stock in Rome, in the Foggia area, in particular in Foggia and Lucera, in the Reggio area in Riace and in Sicily in Castelvetrano in the Trapani area, in Palermo, in Catania and in Ragusa, Curiali is almost unique, they should derive from the Latin word curiale, a sort of ancient notary, of the use of this term we have an example in the Codex diplomaticus Cavensis: ".. In appointments Domini vicesimoprimo main year domni our glorious Gisulfi principis, canteens iunio, fifth tenth indexing. Ante me Petrum iudicem Ursus filius quondam Iannacii Atrianensis , qui dictus est Curiale .. ".
It could have two strains one Sicilian and one Pugliese, it could be derived from a nickname linked to the Latin term curialis (pertaining to a judicial, ecclesiastical or administrative group).
