Was Hitler a Jew?

Hansjurgen Koehler in his book "Inside The Gestapo" published in 1940 describes Adolph Hitler's grandmother, Maria Anna Schicklgruber:

 

"A little servant girl came to Vienna and became a domestic servant at the Rothschild mansion and Hitler's unknown grandfather must be probably looked for in this magnificent house." 

This is supported by Walter Langer in his book, "The Mind Of Hitler" who states: 

"Adolf's father, Alois Hitler, was the illegitimate son of Maria Anna Schicklgruber. Maria Anna Schicklgruber was living in Vienna at the time she conceived. At that time she was employed as a servant in the home of Baron Rothschild. As soon as the family discovered her pregnancy she was sent back home where Alois was born." 

It is barely credible that the infamous Adolph Hitler had Jewish blood and was part of the extended Rothschild family, but then again, when you consider the benefits they gained from World War 2, both financially and politically, a Rothschild connection may not appear quite so ridiculous.
