So many Uchiha must have awakened the Mangekyo before, and who knows , maybe some awakened the Rinnegan but again were forgot because of being warmongers. Mmm are we forgeting this again ? Just in case you don´t remember :

Asura´s chakra + Indra´s chakra + Sharingan = rinnegan

I question to you, how would an Uchiha know who is the reincarnation of either of the Sage´s sons in order to get their chakras and therefore get the Rinnegan ? Sorry, my mistake. But I am sure that some of the reincarnations did awaken it.
