Alois sex life and parentage 

Given his subsequent behaviour, it seems unlikely that Alois reached his mid-twenties before discovering sex. Therefore it seems likely that Adolf may have had other half-brothers and sisters apart from Thekla/Thelka's child. Is there any indication that anyone came forward claiming to be a half-sibling during Adolf's rise to power? If so, what became of them?

Also, how strictly was the ban on Jews enforced prior to 1860? I expect there were illegal immigrants them as there are today. Could a wealthy tobacco merchant (Frankenburger) have bribed officials to ignore his presence?
