Schwab is a fairly common family name in Southern Germany/Austria. It comes from the Duchy of Swabia. There is no one "Schwab bloodline". I've never seen any evidence linking Klaus Schwab to either Marx or the Rothschilds, nor does she present any here.

Schwab is definitely not related to the Rothschilds. That was a meme going around that wont seem to die. It's based on a Mary or Marion Rothschild who married a man name Fred Schwab - I may have the first names wrong - they would be the right age to be Klaus's parents. But they were not. Klaus parents are known. His father was Eugen Schwab.

His mother is a different story, there could be an interesting story there. There is speculation that his biological mother abandoned the family after he was born and it's his father's second wife who Klaus refers to as his mother. The first wife was apparently Jewish and left for America. But her name was not Rothschild, nor Mordecai/Levi/Marx

The video she references at the end is from the BibleTard Bishop Larry Gaiter, who is a mixed bag of truths and total batshit insane bible prophecy :

The real name of Karl Marx is Moses Mordecai Levi.

I don't really care for the rest of the clip, since no sources were given. Also, Schwab family name is not a rare one.

Does she give her sources that she wrote down there?

No sauce no party

No surprise there. Jews are highly inbred. They probably all have common ancestors in the 1400s.
