I know this is a little late. Yes, Frank Corbi as in Corbi's pizza was a head of Baltimore at one time in the 60's I believe. If you look in the Big Black Mafia book released by the United States Treasury Department published by Collins it lists a few names. My father owns a house that one of the mobsters lived in. He lived there in the 60's. I know now there is a minor Philly connection or at least with Joey Merlino when he was in power. All you philadelphia guys keep up the updates.

Thanks
