First point is obviously most decisive. But Mrs. McKnight (their cook) never "came forward with sworn testimony"! The full story is convoluted but incredible. All too briefly: her husband, employed by people connected to the Prosecution, made these claims, which she vociferously denied. The state then jailed her (illegally), freeing her only after signing an affidavit they necessarily wrote (she was illiterate), which she again denounced as false/coerced during the trial. (Albert would also retract his statement before retracting his retraction in highly unclear circumstances.) Even if, as the state baselessly argued, Minola was bribed, Unz mentions none of this.
So her claim about name changes here is basically false: it's a common practice for revolutionaries to change their names or use pen names. Lenin's surname Ulyanov didn't come from his Jewish maternal grandfather, was Russian, and thus wouldn't have "outed him" as quarter-Jewish. 
This screenshot he provides ofc doesn't refer to Eurnekian as a Jewish-Armenian, but as an Armenian, and Tenenbaum as a Jew; totally flies over Keith's head. 
His thread's gist is that the Jews financed notable Bible commentator C Scofield. (That's it.)
Not even touching on the secondary assumption that this impulse directs American foreign policy/anti-Russian sentiment. Simply ignore the entirety of the Cold War and instead focus on speculations about so-and-so seeking revenge on Nick II for oppressing his bubbe...
One of the authors Keith cites give some crucial context: within the social sciences, of which Boas was obviously a part, the trend was the OPPOSITE and egalitarianism was becoming increasingly pronounced well prior to Boas. 
Things to note: 
If we're actually interested in the number of Jews among Australia's "rich people," just continue reading the article: 23/193 = <12%.
Then there were the ceaseless discussions on the H-net forums among academics of topics like antisemitism, Judaism, immigration, etc.
