I've never heard of a Vito/Bonanno connection. There is an interesting parallel 'twixt the two. Just as the Corleones had
one capo who remained loyal in time of war (Clemenza) and another who sold them out to another Don (Tessio to Barzini), the Bonnanos had one loyal guy (Frank Labruzzo) and a traitor who sold out to another Don (Gaspar di Gregorio to Stefano Magaddino). N.B.: Richard Castellano played Labruzzo in the TV movie, "Honor Thy Father," which was pretty good.] And there's the parallel between Michael and Bill Bonanno. But Vito was never kidnapped, or forced to take it on the lam, as was Joe Bonanno, which caused a terminal rift in his family.
