Patrick Hitler, his nephew had a son whose dna was apparently tested, showed Berber (north african) and Jewish ancestry. His grandmother, Maria Shicklegruber(?), worked for a Jew, one Leopold Frankenberger, and he may have been the source.
His friend Emile Maurice was also determined to be jewish. So that is SS numbers 1 and 2. Himmler was no. 5.
Hitler made Maurice an ‘honorary Aryan.
