Looking for the following NAMES (VELTO,RICCI,SPINA,BELLO)

I am looking for the following NAMES for my family history. They are (BELLO, VELTO, RICCI, SPINA, AMBROSINNI, FALOTICA). My grandparents & great-grandparents where both from Italy & I am having a problem on where to go in Italy to get information before they got to the USA. They went from Italy to New York & I have the information after they got to New York but not much before that. If someone could help me on where to go in Italy it would be a great help to me.You can e-mail at clbmav@pacbell.net with any information on where to start in Italy. Or if someone thinks they might be part of my family also please e-mail me & we can both check to see if there is something there.
Since my grandparents & great-grandparents & most of my Aunt's & Uncle's are dead know I am having a hard time trying to get anything done.
Thank you for any & all your help with this.
