We know no reincarnation before Madara awakened the Rinnegan. Simply because since Black Zetsu wanted one to awaken it and then he said he knew he hit the jackpot with Madara and Hashirama's generation of reincarnations. Would have been pretty cool if it was awakened before though. But sadly that is impossible.
