Ivy, good call on Schweihs. The fact is, THE highest ranking non-Italian member, no matter how many people will tell you Murray Humphreys, was actually Gus Alex, who sat on the temporary ruling panel before Aiuppa took over. If an argument can be made that at one point the Outfit's upper echelon included non Italians, he's someone to look at.

Another thing of note. Albert Tocco and RIchard Cain were only a small percent Italian, and both were made men. Never seen this brought up before, so discuss.

Finally, in regards to the OP. I think you're reading too far in to it. The caporegime system is the same as in any other city, except crews also have an Underboss who is seen as as much a senior figure as the capo would be. A good example is 'Johnny Apes' Monteleone, who was seen as leader in his own right. I wouldn't go so far as to call the crews mini-families, or call the made men crew leaders as well.

Kind of sloppy typing, let me know if I need to reiterate anything.
