Something bothers me about the Mangekyo Sharingan

[teeol]

_ Well I don't remember reading anywhere that Madara had children or even a wife. How could Obito be his descendant ?
_ The Uchiha are a clan. That means they record things, like their history, members. They have archives. I don't get how they could have lost that knowledge. And I do remember reading that Madara and his bro were the first ( as in the very first ever ) to unlock it. I'm just looking for a suitable answer/theory

Only Kurama knows the full story of the uchiha clan but he has no intentions of reviling anything

My theory was that you needed to fully master the sharingan and then experience the trauma. It explains why MS was achieved only a century ago. All the MS user we had seen so far were genius - madara, izuna, shisui, itachi, sasuke. Obito clearly didn't fit in that group. So he blew my theory. A trauma alone can unlock it but here is the catch, why wasnt MS achieved ages ago then, before madara's time ? Lots of Uchiha would have lived traumatizing experiences, the world was at war
