V. Blunda proposes that this surname comes from the Greek Dòmna, a feminine personal name of the Byzantine repertoire preserved in the onomastic tradition of the Mediterranean as a baptismal name applied to women, which crystallised later as a surname in Greek-speaking eastern Sicily during the medieval period.

E. Rossoni associates the surname with the Palermo area, with presence documented in localities such as Gangi, Palermo, Cefalù and Castellana Sicula, although his entry is incomplete and does not allow the complete etymological analysis to be recorded.
