Carmine Galante was never a Boss - he was the leader of dissident faction in the Bonanno Family. Philip Rastelli was the real Boss.

Salvatore Giancana among others never had complete control of the Chicago Outfit, from the early 1950s it was Anthony Accardo and Paul Ricca.

Joseph Colombo was never the Boss of the Colombo Family, it was Joseph Gallo - the crazy one.
