I would submit that the Jewishness of the Rothschilds is essentially unimportant

Revelation 2:9, "I know thy works, and tribulation, and poverty, (but thou art rich) and I know the blasphemy of them which say they are Jews, and are not, but are the synagogue of Satan."

And compare that verse to the Satan Summoning His Legions that Baron Rothschild and Satanists Abramovic posed in front of.
