Apollonia is very rare nowadays. There are just 4, 000 of them living in Italy and less than five born every year.

This name is also Spanish.

I have researched birth certificates-- and one baby girl born 1812, Italy bore the first name, "Apollonia." I believe that it is safe to say it has been in Italian usage for a number of years... perhaps even longer than what I reported.
