Where the Alessi surname comes from
Alessi comes from a personal name: Alessio, in Greek Aléxios. It comes from a verb that means “to defend, to protect,” and Alessio originally meant something like “the one who protects.”
In the South, Greek names had been at home for centuries. When surnames began to settle, the children of an Alessio became “Alessio’s folk”: the Alessi. In so many Sicilian surnames, the final -i means just that, “the family of.” A town proves that Alessi is the Sicilian way of saying Alessio, and the PDF tells you which one.
A saint under the stairs
