My family name is AVONA. My grandprents were Gaetano AVONA and Dorothea CATANZARO of Menfi, Sicily. Gaetano was the son of Gaspare AVONA and Calogero PALMINTERI of Menfi or Sciacca. Dorothea was the daughter of Leonardo CATANZARO and Ninfa MOSCITTA of Menfi. They came to NY via Ellis Island in 1913 with two children. For about 7 years they resided in Brooklyn and in 1920 were living on Shelter Island, NY where they settled and raised their expanding family. I am piecing together some of the extended family and have been told that all the AVONAs in the US are related. I can't attest to this though. Also there are AVONAs who came to the US through Mexico and Montreal.
I would be happy to exchange some of the information I have although it is currently somewhat disorganized.
