I gotta ask, if I showed you guys a Sicilian family with like, 20-30 members, would you consider them a crime family?

Also consider families in the past like SanJose, San Francisco, Denver, Dallas Ect...
Did any of em have more than 20-30 guys?
These families more resemble crews than anything, but were considered families. What exactly constitutes a family? Or cosche, or ndrine? What exactly makes em different?
