Ok - dumb question/comment time....

I'm going to preface this by saying i do have a slight hearing problem, and AMC seems to be one of those channels that i have to turn way up to hear...

But whenver i watch this scene when Vito is introducing the other Dons - it seems like he makes a reference to a Corleone Family from Brooklyn.

Am i hearing things?

And if not, could this be the missing 5th family?
