From the etymological point of view, however, the term ciavaglia consists of a deverbale of the verb ciavagliare, which, together with verbs such as tartagliare, ciangottare, barbugliare, farfugliare, etc., seems to derive from an onomatopoeic voice. As far as the surnames in question are concerned, therefore, these are the surnames or personal names of the founders or of the nicknames attributed to them.
