I decided that there were enough Mazzella's in history to make Wikipedia, so I created a few Mazzella articles and a disambiguation page that lists them all.
As more historic Mazzella figures emerge, I will add them. You may add them also.
Famous Mazzella's are, Cardinal Camillo Mazzella, Archbishop Enrico Mazzella, Intelligence Minister Luigi Mazzella of Italy, Edward Mazzella Jr. of Cantor Fitzgerald who died on 9/11/2001 at the World Trade center in NYC, Guitar Virtuoso Anthony Mazzella.
