Taken from a March 10, 1959 Social Services report from the Welfare Council of Metropolitan Chicago. Here is undeniable proof Ambrose existed in the 1950s and on the streets of the Near West Side neighborhood. They were assigned to Hull House which was right in Little Italy and close to Taylor Street where Ambrose was said to have originated. All gangs were assigned the social services houses closest to their territory at the time, since Ambrose was given Hull House it means their territory was within the vicinity back in the 50s. If they were in Pilsen they would have been assigned to Howell House.
