Several countries – like Germany, Sweden, Iceland, China and Japan – restrict names.
In Iceland it’s about meeting certain rules of grammar and gender, and saving the child from possible embarrassment.
Similar concerns about child welfare are present in Germany, where a Turkish couple were not allowed to call their baby Osama Bin Laden.
One couple named their baby Berlin after the city in which they met, prompting the registrar to mount an objection. He eventually relented after the family’s lawyer pointed out that the courts had allowed the name London. In Germany you wont’t find the names Merkel, Schroeder or Kohl, because surnames are banned as first names.
The name 4Real fell foul of authorities in New Zealand, because names cannot start with a number. A judge there also made a young girl a ward of court so that she could change the name she hated – Talula Does The Hula From Hawaii.
There have been 20 people named Noun, 458 named Comma, 18 called Period, but only one called Semicolon in the US. American parents can pretty much name their child anything.
