Yea,there are FBI files on MaryFerrel I believe of Tommy Ryan, Jerry Catena , Mike Miranda, and Lombardo having various meets discussing the Bananas War and how they didn't trust Carlo and how he and Lucchese basically orchestrated that whole war from the outside. When I say they, I mean Eboli and I think Miranda and Lombardo, I'm not sure. But Eboli felt Catena was bowing down to Carlo and setting him (Eboli) up to be killed, along with the others, so he could be the only legitimate successor to Vito if he came out and named a successor or if he never came home. It was suspected by the others of the Genovese triumvirate, that Catena was basically setting himself into position to be named boss by Carlo, if Vito didnt or wasnt able to do so.
