Giuseppe Commisso (u mastru) and Antonio Commisso (l'avvocatu) are brothers who were born in Siderno -- the latter is the one who was arrested in Woodbridge, in the Greater Toronto Area, in 2005. The poster LittleJoeShots believes or knows that the Commisso brothers in the GTA Siderno Group are cousins to Antonio, which would mean that Giuseppe is also related to the three brothers.

Antonio and u quagghia are supposedly cousins, which if true would mean that Giuseppe is also a cousin to u quagghia. Giuseppe's wife's name is Clementina; so her side of the family may need to be explored if you're doing a family tree.
