Is there any truth that European Jews were actually a mix of Jewish merchants, as well as Jews exiled by Romans from Israel who then married Italian women and who later during Inquisition migrated into Eastern Europe,Germany,etc ?
That I can't speak to.
But, regarding Jewish racketeers operating upstate, Utica's underworld also had their fair share of guys, many of whom interacted with, or were 'with' regime bosses Sal and Joe Falcone.
