也看到说，Hitler's lawyer Hans Frank在他的回忆录说希特勒父系爷爷是犹太人

没读过Hans Frank 的Memoir (1946), 新闻里这么说的

Study suggests Adolf Hitler’s paternal grandfather was Jewish - The Jerusalem Post (jpost.com)

The study, titled “Aus den Gemeinden von Burgenland: Revisiting the question of Adolf Hitler’s paternal grandfather,” which was published in the current issue of the Journal of European Studies, examines claims by Hitler’s lawyer Hans Frank, who allegedly discovered the truth.

 

Hitler asked Frank to look into the claim in 1930, after his nephew William Patrick Hitler threatened to expose that the leader’s grandfather was Jewish.

 

In his 1946 memoir, which was published seven years after he was executed during the Nuremberg trials, “Frank claimed to have uncovered evidence in 1930 that Hitler’s paternal grandfather was a Jewish man living in Graz, Austria, in the household where Hitler’s grandmother was employed,” and it was in 1836 that Hitler’s grandmother Maria Anna Schicklgruber became pregnant, Sax explained.

 

“Frank wrote in his memoir that he conducted an investigation as Hitler had requested, and that he discovered the existence of correspondence between Maria Anna Schicklgruber – Hitler’s grandmother – and a Jew named Frankenberger living in Graz. According to Frank, the letters hinted that Frankenberger’s 19-year-old son had impregnated Maria Anna while she worked in the Frankenberger household: ...that the illegitimate child of the Schickelgruber [sic] had been conceived under conditions which required Frankenberger to pay alimony.”
