For Lemursrule's theory of Yhwach and Yamamoto being brothers, I don't see how that would be likely at all, even possible in the first place, as Shinigami (Yamamoto) are spirits and Quincies (Yhwach) are humans.

As for the +/- 800 years between Yhwach being sealed away, and the Quincy massacre, I guess that was the period of continuous attempts from the Soul Society to stop the Quincies from destroying souls and messing with the balance, and the wars that followed since neither side wanted to give up.
