Just found that Site, few minutes ago - I am Italian , leaving in Belgium.
I am from Rusteghini in Italy where I still have my family house. I have thousend of informations about Cavaciuti roots , including family trees for part of the family written by don Santino Cavaciuti ( Priest and Philisophy Professor in Genova University ). I am going to check out all the messages request of this board and try to give some infos. Frank born in Torino sound a bell to me , might be connected to the "lunghi" ( Tall ) branch of the family.
Any questions do not hesitate. I ll be back.
