I found the original source of the info.
"Adolf’s father, Alois Hitler, was the illegitimate son of Maria Anna Schicklgruber. It was generally supposed that the father of Alois Hitler (Schicklgruber) was Johann Georg Hiedler. There are some people who seriously doubt that Johann Georg Hiedler was the father of Alois… (an Austrian document was) prepared that proved Maria Anna Schicklgruber was living in Vienna at the time she conceived. At that time she was employed as a maid in the home of Baron Rothschild's mansion in Vienna. As soon as the family discovered her pregnancy she was sent back home… where Alois was born."
The information came from the high level Gestapo officer, Hansjurgen Koehler. The Book published in 1940, under the title "Inside the Gestapo". He writes about the investigations into Hitler’s background carried out by the Austrian Chancellor, Dolfuss, in the family files of Hitler.
