Wow ... reading these sometimes really weird names I think I can be glad to live in Germany, huh?! Here it is plain and simple forbidden to give a child a weird or in any other way unorthodox name. Some years ago a mother wanted her child to have the name Pumuckl after a
comic-character from a children's-book, but the registry office just said "no!". I'm not quite sure which name the kid got in the end, but thankfully it was definitely another.
In Germany you can't even give your child a name that doesn't show the sex of the child (for example the names Kay, Toni, Eike, Dominique and many more are both male and female) - if you do so you have to give a second name that shows the definite sex of the child. And you're not allowed to give a name of the other sex.
Aaaaand as a 3rd you can't give your child a name that has a 2nd meaning in German - a german registry office for sure would never have allowed it to name a child "Gerücht" (= Rumour ...)
Unfortunately that also means that many really nice names aren't possible because they are not common yet in Germany
