I suggest we add Machievili to the Grand Masters page. As he is the leader of the Assassins in Rome as stated in that interview. If he founded the Assassin Guild in Rome, then obviously he is a Grand Master by default. :P From the interview, "[Nicollo's] the leader of the Assassins in Rome when Ezio arrives and he's not going to just let Ezio come in and take charge.
