Yes that would be great Maranzano is still an enigma, He had strong connections to Chicago, but he wasn't long in the US he came after WWI.

Later ill post some additional stuff regarding Chicagos pre-Prohibition era Dutch racketeers, although Ill need some help from you regarding the Dutch names.

Regarding Capone...if you ask me there was one "small" difference between leaders like Colosimo and Torrio, and the younger ones like Capone. They all literally inherited many lucrative operations and connections from their "predecessors" or allies from the former Irish or multi-ethnic mob, mostly in a peaceful way, but the difference was that the old guys like Torrio trusted all of their so-called loyalists probably too much. For example, Colosimo was probably killed by his own loyalists, while Torrio was almost killed allegedly by other former loyalists who in turn previously betrayed him to the cops, an action which resulted with Torrio killing their leader. On the other hand, Capone already knew this and chose his loyalists carefully and eliminated everyone in quite violent style, which was used to send message to the rest of their rivals. And as you already know, during those days, besides the Italian CN and Camorra, there were numerous other clans and so someone needed to place them in line under one top administration. And so thats how Capone's (multi-ethnic) Outfit was born with the Italian brotherhood at the top, meaning the bloodbath was inevitable. According to some sources, Capone allegedly was convincing other Midwest Italian bosses to do the same thing (hence Milton Rockman in Cleveland and the Purple gang in Detroit). Thats why I always say that the Chicago group was "slightly" unique then the rest of the Italian families, since the Chi boys worked with everyone and almost "breached" the limits between the Italian brotherhood and their trusted non-Italian associates. Or as Outfit non-Ital leader Murray Humphreys once said "I remember how it used to be in the old days, with us, when Al (Capone) used to run us guys all over. We trusted each other, see?!"
