1) Charlie the Wop:
Charles Carrollo, boss of the Kansas city family
2) Joe the Wop:
Serafino Sinatra, aka "Joe the Wop" English, member of the Yonnie Licavoli group in Toledo (not sure though whether this group was a small independent family during Prohibition at the time, or whether it was already a crew of the Detroit family).
Charlie the Wop is correct.
And although there are many guys with the name "Joe the Wop" in various cities (so I can't fault you on your choice, Dwalin,) that Joe the Wop is not the other guy on this list. Because there is a "Joe the Wop" with the Gambinos - his name is Joseph Gennaro.
So pick another name for the second man....But that was a very good try!. You got one out of two, so far.
