Magliocco´s underboss was "Big" John Misuraca. He stepped down in 1963 (before Magliocco was deposed) because he wanted to concentrate on his buisnesses in Florida and NJ. When Colombo was made boss, Salvatore "Charlie Lemons" Mineo stepped up. Just like Pmac is saying, both Misuraca and Mineo were extremely low key. Two old timers.
