@oscarthedago,what does gambino marrying his cousin have to do with his capability as a boss of a cn family?. Nothing.
Same with the other point, everyone has 0 power without their friends. That's what politics is all about. Climbing up the ladder making the right friends and getting rid of the right enemies. In his time he was the most powerful boss and it doesn't happen by accident. Not in the mob and not in anywhere else in life.
