"You're probably right but i've heard before that the Genovese family were always the largest the only reason the Gambinos were more powerful at one point was because of Carlo controlling most bosses on the commission ."

I strongly believe the Gambinos were the biggest (in numbers) between 1930 and 1980. Of course, the bosses never informed the authorities about this. So I could be wrong, Cam. And besides, I´m not Italian...
