It's from The Don: The Life and Death of Sam Giancana, by William Brashler.

I now think that Potenza is the handsome guy in the ANP photo sitting and smiling in the back right. Might be getting close to 7 now...

1. Amato
2. Accardo
3. Pranno
4. ??? (Gagliano?)
5. ??? (Amabile?)
6. Potenza
7. ??? (Battaglia?)
8. ??? (Adduci?)
9. Cerone
10. ??? (Ferraro?)

Can we figure this out already?!

How sure are we that #1 is Amato, and is this not looking more like a Taylor St affair?
