Tommaso Gagliano, I find to be the most secretive boss from after the Castellammarese War till his death. He was part of the Morello crime family till Gaetano Reina split from that family to form his own family in the Bronx. We know that his cousin Salvatore Gagliano became an informant around 1914/15 against members of the Morello family, amongst them were Ignazio Dragna (Jack Dragna) and his brother Gaetano Dragna. Both of which fled to California soon after. Despite this Dragna and Gagliano had a friendly relationship for the remainder of their years.
