Your last name is karwinsky and you didn't know you were polish??
Just kidding, but seriously no there was never really a large presence of Polish OC here in the US, at least not like the Irish, Jewish, or Italians. but in recent years there have a been a couple of small groups of polish criminals that have gained a little notoriety , one out of Brooklyn and the other out of Philly, neither seem like they were ever a serious OC element though. heres a little bit about them-
