This is interesting. It confirms that my surname is indeed of German origin, but today Twerdys are mostly found in Austria and Canada, where they still remain very rare: three in a million in Austria, two in a million in Canada. Only .21 per million in Germany. And that is apparently it, aside from a few individuals in the USA. Which leads me to believe that there may be less than a hundred Twerdys in the entire world.

Interesting concept, i wonder how accurate it is. It got most of my family right.
