After further research I found that Joe had a brother named Antonio Magliocco, Sr. who started what is now the largest liquor distribution business in NYC. It is called Peerless Wine & Liquor and is currently run by Antonio's children.

I am not sure if Antonio Magliocco Sr. was a made man.

I have also read about an Ambrose Magliocco but am unsure of what his connection is.
