Family boss Sebastian (John) La Rocca's buddy -- Giuseppe (Joe) Sica

Joe Sica also just happened to be Lucchese acting boss "Little Al" D'Arco's cousin.

When D'Arco struggled to get made with the Lucchese, Joe Sica offered him to move to Pittsburgh and be inducted over there.

Yep. And if I remember the book correctly, D'Arco also stated that although it may have worked out, he declined his cousin's offer for two primary reasons. #1, D'Arco and his family liked NYC and really didn't care to move elsewhere. #2, His cousin could be a little overbearing and demanding, and D'Arco wasn't sure he could handle that.

But on review, judging from the way things turned with the Lucchese crew, I'm sure D'Arco lamented that decision many times in later years.

He would have probably prospered in Pittsburgh.

Another very 'quiet' capo of the LaRocca Family was Lou Volpe, who made money - but very little headlines - in the later years...

I guess Lou learned valuable lessons of when he and his brothers first operated back in the 1920s-30s, an era where the Volpes saw much blood and death, both to others, and among themselves.

To be fair, all the Pittsburgh capos were notoriously quiet, the family in general kept a very low profile and made a lot of money.
It wasn’t until the Porter trial and the Rincon casino story that they really made national headlines.
Even when Mannarino was part owner in a Cuban casino and LaRocca had his ties across the country from NY to Detroit to Chicago to California, they didn’t get noticed much.
