The writer of the article should do better research. He claims Russell Bufalino and Bill Bufalino were brothers, when if fact they weren't even related. According to Sheeran Russell did allow Bill to say he was his nephew, because that would give him more clout when dealing wiseguys supposedly..
They were related could be his cousin, Russell did have many brothers.
Maybe distantly related, but not first cousins. I read the book and many articles and all stated that Bill was not related to Russell, but it wouldn't be the first time an error gets continuously repeated..
