My wife is a Procaccino and her family was from Colli A Volturno and lived in NP at 11th and Erie area.
Her cousins include the Leva family. We know Antonio Leva. He married Angelina Procaccino.
Any connection. Also, the Leva name is probably jewish is some way - Levy. There is a large jewish ghetto in Rome and many names are now italianized like Salomone which was Solomon.
