Did Rocky Marciano once box his brother?

In answer to this question Rocky boxed against his brother Sonny Marciano on many occasions, but never in official fights, only in sparring and infamously on an exhibition tour, where his brother illegally took on the identity of another amateur fighters, for this Rocky served a one month suspension in all states except NY where he had most early fights.

Rocky Marciano's true amateur record was/is 9-4 (8KO's), never 8-0, 30-0 (according to Sullivan's badly written book), 8-4 .

The confusion over 9-4 vs 8-4 is extra fight not included in his record because fighter Ralph did not show so naturally Rocky won by DQ!
