Besides, when I've thought it throught, I was actually surprised that Sasuke didn't know anything about Madara before Itachi told him, despite the latter and even Obito in his young age (who recognised Madara's name as a legendary Uchiha immediately) clearly having enough informantion about him. However, could be the case that the history of the Uchiha clan was taught only within the clan itself, so Sasuke didn't have enough time to learn it before the clan was slaughtered, and then there was nobody for him to teach.
