That sent me down a rabbit hole. Seems like having rules on what you can name your own kid are in place in several European countries. From an American perspective, I find this simultaneously off-putting (you are going to tell ME what I can name MY OWN child?!!) and also probably a net positive. I've often thought that a lot of tragedeighs could be averted if hospital registrars ran the names through a checker and pushed back on the parents to verify they really wanted that. But that's based on an assumption that it's often not intentional.
