Question about Tiste - mostly through RG

I just finished the 3rd book/section of Reaper's Gale, and am just a bit confused about the whole relationship between Mother Dark, Father Light, Menandore situation. I know it's come up a ton in previous books as well, especially in Midnight Tides where it reveals that Scabandari (Tiste Edur) was actually the one to betray Silchas Ruin (Tiste Andii) and not vice versa. But I'm confused about the family line with Anomander and his two siblings (Silchas is one but Scabandari is not? I thought those two were brothers which made the betrayal worse but apparently not?), and then Menandore and her sisters, who are maybe related to the Edur but it's unclear? And Menandore's sisters were the ones stuck in the Azath house in Lether that Silchas escaped from, correct?

Without giving spoilers for future books, could someone just give me a brief family tree of the Tiste Andii/Edur? If it's spoilers for later just let me know, but it seems like we've gotten tons of information about it already and I'm just having difficulty piecing it together and remembering from previous books/prologues and such since there's so much that happens.
