Great work! Rich information.

A few comments from a European perspective.
He also works closely, I believe, with Charles "Charlie the Blade" Tourine. Especially in Cuba.

From that time there is also a connection through Cellini to Joe Nesline from DC. Later, these two also have activities (gambling and boxing) in Europe with local groups (especially in Hamburg, Germany and Amsterdam, Netherlands).

I don't know if it is an exaggeration to call Joe Nesline a member, but there are some cross connections. In any case, there are some connections from the European activities back to the Genovese and the Boston guys. But the original connection came through players from Cuba and Lanskys operation.

Another interesting aspect is that the son Louis Schrager is today a very rich real estate mogul.
