Im not sure terranova was ever brought into luciano's syndicate bc he lost face during the masseria hit. He was the driver n got too nervous after the hit took place n couldnt drive. Bugsy siegel shoved him outta the way n he drove the get away car. Gaetano ricci wasnt he a chicago gangster? I mighy have him confused

Coppola was also listed as the successor to Terranova on the Genovese Family Chart at the Valachi hearings.
