Rebecca,
My name is Mark Anthony Pezza and my family is related to Fra Diavolo. My father's parents and his older brother came to the US from Itri. I personally have little knowledge of the family tree but I have forwarded your message to my brother Gregory who is in the process of creating our tree. If I remember correctly he may have the lineage almost complete all the way back.
I'm not sure when I will here back from him. He just got married and I'm not sure if he's back yet.
If you would like email my @
MarkPezza@Cox.net and I will aslo forward your email address to him.
Mark
