The really powerful bloodlines stay hidden, I doubt you'll find anything. We don't know any of their names. There is a whole hierarchy above the rothschilds, payseurs, and the "13 bloodlines".
Read this, it is the most interesting AMA from a cabal insider I have ever read. They claim to be from this upper level of the hierarchy.

From what I gather the higher level has a completely pure bloodline, possibly rh null blood type, while the ones we know are "mixed" rh negative.
