A Lot of history but they are way past defunct. Recently besides Gagliano who pretty much had a telescope up his ass from the FBI with his "snow cone sniper van", I'm pretty sure the last guy that had anything to do with Marcello when he was still the boss was Kent Brouillette aka "Frenchy". He ran prostitutes in the French Quarter (Not a made guy, just an associate). I think he was stabbed to death in 2014-15 by some drug addict he had living in his house. He has a book written about him called Mr. New Orleans, not sure how much of it was true but he was in fact the cousin of the then Governor Edwin Edwards who also spent time in prison for racketeering.

Aside from that anyone that says NOLA is still functioning is living on hopes and dreams or some weird fantasy.
