William was born in Boston in the neighborhood of Dorchester. A crime ridden area notorius for it's connection to the Irish Mob, most notably the Winter Hill Gang. He grew up never knowing his father, whom his mother always told him had died shortly before his death. What he didn't know at that young age is that he would be propelled into a similar line of work in later years. He would unknowingly follow into the footsteps of his pops in the very same organization as well.
