There were so many competing "dons" in the early 1900's in Detroit. Aside from the Giannolas and Adamos, there was Ferdinand Palma, who managed to have the job of a police detective before being indicted in a criminal scam of voter fraud and human trafficking. There was Francesco D'Anna and his brother Salvatore. Salvatore, and Francesco for that matter may have just been lieutenants of the Giannolas though. A Carlo Cacela was a Giannola street boss who operated in Detroit. Both the Giannolas & Adamos were based in Ford City which was actually outside of Detroit. And another supposed don was Joe Moceri, which may explain Leo "Lips" Moceri and his closeness to Detroit mobsters, he may have even been one, despite later settling in Cleveland with Licavoli, who has a bloodline dating all the way back to Detroit.
