The rise of Nazism again is a very disturbing occurrence.

What an interesting article, may the growing youth of today that are Nazis be forced to learn about the evil of that inhuman Adolf Hitler

He also hated lots of other things. Good riddance.

Warburtonbogan, absolutely. I mean, we literally fought a war against this. 😑

UnopposedYogi27101, It's upsetting that we can only put one 'thumbs up' each to your comment.

RushMama2112, his own nephew fought against him in that war.

Hate, Hate and more Hate the Nazis had to be stopped basically because of their crimes against humanity and the freedom that was and still is the right of every person that walks the Earth. Evil on this scale should never be allowed to thrive anywhere, unfortunately as we all know it does, we should have learned to tolerate and respect other cultures and listen more to each other’s opinions.

Wannabe Vulcan, there is an unsubstantiated history that implies or states that the Hitler family members in the United States made a pact to not have children and ensure the lineage ends with them.
So was there a pact?
So the question now is whether Peter Raubal, Heiner Hochegger, and Alexander, Louis, Howard and Brian Stuart-Houston had a pact not to have children. This is where the book by David Gardner, and an accompanying article come in.
The Stuart-Houstons (who live in New York) likely have had no connection to their cousins Peter and Heiner (who live in Europe), as their father very much wanted to distance himself from his family. Peter is also in his 80's and Heiner is in his late 60's. As neither of them have had children, it's possible they independently decided not to have any, but it's unlikely it was part of any sort of pact.
Finally, that leaves the three living Stuart-Houstons - the ones most likely to have made a pact. Gardner writes:
