From what I've read once the FBI found out the 5 family structure of NEW YORK LCN, the families have been named after the guys who were bosses at that time and the name has stuck no matter who's in charge.

While Gambino, Genovese, Luchesse and Bonanno were unquestionably heavy hitters, can the same be said about Colombo?

In the era of mafia big shots (50's-60's )was he held in that high regard?

Did he get boss position because he ratted to Gambino about Bonanno's murder plot?

Where was he during Gallo/Profaci war, was he actively involved?
