I remember reading that Gotti weighed in on the conflict involving Ray Jr and the Boston guys as well. Gravano testified about it.

Also, something interesting I found while looking for that Gravano testimony is an article about how James Martorano was the Patriarca's link to the Genovese and he was in talks about killing Sammy's family.
