Cafa, almost unique, is probably due to an error in the transcription of Cafà, which is specific to Gela, it should derive from the name of the Byzantine city of Cafà on the Black Sea, probable place of origin of the family, perhaps escaped with the arrival of the Turkish, but we cannot exclude a derivation from a nickname originating from the Arabic term akfàs (with crooked legs), Al Akfas is also an Arabic name and surname.
