I've just finished watching the six seasons of The Sopranos. So much of the show revolves around Tony Sopranos' desires to have a "normal" American family life, despite the fact that the lifestyle is funded by his criminal activities as Don of the northern New Jersey Mafia. A lot of that tension, in turn, comes from the character of his daughter, who has seemed to escape that life by going to Columbia and then law school and becoming educated and employable in the straight world. And a lot of the ultimate tragedy of the show is that Tony, a sociopath who often justifies his murderous Mafia life by rationalizing that it's for his family (much like Michael Corleone in The Godfather, although Tony never thinks he himself is going to be able to become legitimate), ends up in the last scene (although famously we don't really see this on camera) being shot in the head sitting in a booth in a diner with his wife and son, just as his daughter, Meadow, walks in the door. He hears the bell over the door ring, looks up, and the screen goes blank for ten seconds. We are left to imagine the horror he has inflicted on the family he claimed he was protecting.
Anyway, Meadow Soprano is played by Jamie Lynn Sigler.
