The surname Cario has a stock in Naples and one in Catanzaro in Falerna, Nocera Terinese and Lamezia Terme, it should derive from the Latin name Carius, understood as a comparative of the adjective carum (dear, beloved), we see its use in the writings of the poet Latin Catullus: ".. Fifths, tibi vis oculos debere Catullum aut aliud si quid carius est oculis, eripere and freights, fine quod carius illi est oculis seu quid carius est oculis ...", even when he speaks of his beloved Lesbia: "..Y quicquam cupido optantique obtigit umquam // insperanti, hoc est gratum animo propria. // quare hoc est gratum nobis quoque, carius auro // quod te restituis, Lesbia, mi cupido. ..", name probably attributed to the founders , less probable, but not impossible, a derivation from a nickname originated from the Greek term ?????? karyon (walnut), we must however consider that in Latin times the nut fruit was considered as a bearer of wisdom, so a nickname of the kind, which should have been pronounced as Karuo, and not Kario, could have been the equivalent of the essay .
