As the owner and founder of Yamagakure, I can assure that information of that nature is going to be difficult to get your hands on. Ryun was too busy leading the village and restoring the clan to have recorded information about Izanagi, and, realistically, probably wouldn't have even if he had the chance. The side-effects are too drastic. The Second Yamakage wasn't an Uchiha, and by the time of the FC, the Third (which is Ryun's daughter) doesn't even know Izanagi herself, so it is unlikely that'd she'd have knowledge to pass on to other members of the Yamagakure branch of the clan.

Just thought I'd insert that.
