What does Beatrice mean?
Italian form of Latin Beatrix. Beatrix most likely began as Viatrix ('female voyager, traveler') and was reshaped under the influence of Latin 'beatus' ('blessed, happy'), giving the enduring sense 'she who brings happiness' or 'blessed'.
What does Aria mean?
From the Italian word 'aria', meaning 'air' and, in music, a solo melody or song. An identical-looking name also exists in Hebrew (related to 'aryeh', lion) and Persian, but the modern popularity rests on the Italian 'melody' sense.
