Agari is almost unique, Agario has almost disappeared, Agarini, very rare, seems to be from Livorno, Agarinis, always very rare, is Friulian from upper Udine, in some cases could derive from the Walser toponym of Agaro (Walser are populations of Germanic origin) that around 900/1000 have settled in the Alpine territory), but normally should derive from the medieval name of Jewish origin Agar (see D'Agaro), the Friulian lineage could also derive from the Friulian term agar (gully) perhaps to indicate some characteristics of the home of the progenitor.
