Did Hitler ever have any Jewish children?

I would not think so, but according to the Translators notes in Mein Kampf (by A Hitler), Hitler's father, Alois Hiedler, was born illegitmate. It is "possible" that Hitler's unknown grandfather was Jewish. How's that for irony? ___ Are the question and answer referring to the same Hitler? My reading of the question is that the question refers to Adolf, not to Alois.
