You Adolf Hitler Jewish

If you're asking if Adolf Hitler was Jewish, it's possible but extremely unlikely.

Adolf Hitler's grandmother, Maria Schicklgruber, was not married when she gave birth to Alois Hitler (Adolf's father). It's not 100% clear who Alois's father was, but it's generally accepted that Johann Georg Hiedler was the father; another possibility is that it was his younger brother Johann Nepomuk Hiedler. Johann Georg eventually married Maria; but he was a traveling salesman, so Johann Nepomuk raised Alois- Maria died when Alois was a child. Since Alois was illegitimate, he was born with the name Alois Schicklgruber; when he was nearly 40 years old, he went to the church and had himself legitimated as Johann Georg's son, and took the name Hiedler- but it was somehow misspelled as Hitler, and Alois kept it.

After Adolf Hitler took over the Nazi Party and started to become famous for his antisemitism, it appears that some people found out about Alois's questionable ancestry and tried to claim that Alois was actually half Jewish. The claim goes that when Maria conceived Alois, she was living in Graz and working as a housekeeper for a wealthy Jewish family; supposedly she had relations with one of the family's eldest sons. However, this doesn't really seem possible since Jews had been forced to leave Graz hundreds of years earlier (Austria and Germany both have long histories of antisemitism) and were not allowed to return until well after Alois was born. There's also no evidence that this Jewish family existed, nor that Maria ever lived in Graz (she lived almost her entire life in one small town in Niederösterreich, over 100 miles away).

There's an interesting side story regarding the Hiedler brothers. It's possible that Johann Nepomuk was Alois's actual father, and indeed, the fact that he raised Alois could possibly point to that; however, he was already married, so it would've been an extramarital affair. It is possible that he had his older brother take the credit for fathering Alois to save his own marriage. The generally accepted story is that Johann Georg is the actual father, however, and that Johann Nepomuk raised Alois simply because his parents weren't around.

Lastly... Johann Nepomuk Hiedler had a daughter of his own named Johanna, and she married Johann Pölzl. They had a daughter too, and her name was Klara Pölzl. Klara Pölzl later had an affair with and then married Alois Hitler (she was his third wife- and he had a long history of infidelity). Their third son was Adolf Hitler.

One way or another- Adolf Hitler's parents were pretty closely related. They were probably cousins, but may have been uncle and niece.

And if Alois hadn't legitimated himself and changed his name to Hitler, Adolf Hitler would've been born with the name Adolf Schicklgruber- which certainly doesn't have the same ring!
