As far as i know they were not made guys here in the USA. Not sure if they were made in sicily. All i really know about them is that they were at the time younger relatives of the Gambino's and from what i've read they answered to Rosario and Erasmo Gambino. But i really don't know what their mafioso status/ranking was back then.

Antonio was convicted in the case but Mario was acquitted.

Another big name was Francesco Gambino from Torretta....definitely a high ranking mafioso and was sentenced to i think 40 years. He died a couple of years ago in prison.
