Family name origins & meanings
- Italian (Sicily) : from a personal name which de Felice suggests may be a fusion of two saints’ names: Cosma + Damiano, with a loss of the last syllable of one and the first of the other, but which Caracausi takes to be a regional variant of the Late Greek personal name Kosmas (see Cosma) or a short form of an old personal name beginning with Kosm-. He suggests that alternatively it could be derived from Arabic Quzmān.
