Moe, Shemp and Curly were all brothers.
And all from Brooklyn, too!
A little trivia - there was at least one movie in which Moe, Curly and Shemp all appeared together. After Curly had a stroke (and was replaced in the act by Shemp) Curly appeared in a scene involving a train (as an extra). He was "sleeping" in a train car with his hat over his head (and the hat was removed). It was sad to see him like that (it was very apparent that he had suffered a stroke).
