Which Sopranos actors have passed since aired?

Exactly 7 months after the last post in the thread about Johnny Cakes committing suicide I wonder; How many Sopranos actors have passed since the first episode began?

The only two I can think of are John Costelloe(Johnny Cakes), and Nancy Marchand(Livia Soprano). What other actors have passed that you know of?

Also, if this subject was posted elsewhere I apologize.

Are we talking about regulars here?

Im not aware of any dying..

Any actors or actresses in the series. From the beginning to the end.

A few have gotten into some "real" shinnagens, and a couple are in prison I think, but I don't know of any others that have died.
