Arella, extremely rare, almost unique, would appear to be from the Campania and Calabria areas, Arelli, it has very old roots both in the Pavia area, in Veneto, in Campania and in Puglia, Arello is practically unique, should derive from the Latin name Arellus, Arella, of which we have an example in a medieval satire: "..Improvisa, satis reverens habeare futura. // Si vel tussicula leporis vexatus Arellum // Aut Dasium, fratres inauspicious sidere natos, // Sub your tecta voces. Cosconi, fidis Arello? // .. ", a name which may have originated from the hypocoristic forms of the name Ares, or from medieval dialectal alterations of the name Aurelius.
