I lost any ties I had with Pittsburgh when Charlie died. I know that Michael's son is an attorney and has never been involved. I don't believe either of Jo Jo's son-in-laws are active although one is an Amato. I've heard that Sonny is or was the last Boss and I believe he's still alive.
Unfortunately FOH, Sonny did pass away in July 2021, last Boss, last living “made” guy, supposedly.
