Ciro, I'm reasonably sure theres no single family in Alia. Any activity there is likely to be a spin off from one of the villabate clans. This is based on a couple of remarks made in Giornale Di Sicilia articles. No idea about marineo I'm afriad, but given the towns location id imagine its a real mafia stronghold. Why do you ask about these towns soecifixally? do you have relatives there. My bro lived in Bolognetta near marineo for around 5 years in the late 90s.
