Man, all this drama. The parents should name a child they’ve had. That’s my opinion. You shouldn’t have to ask permission from an external person. No fan of any of these characters, feels like something out of an MTV reality show, that includes the Queen.
There are some few situations in which a hard-and-fast rule does not apply. Some nations other than ours have rules about naming conventions, enforced by law. Even the state of New Jersey, USA, stepped in to this dispute about a baby name:
New Jersey Parents Who Named Child 'Adolf Hitler' Lose Custody of Newborn
Baby Names That Have Been Banned Around The World
There are some doozies on this list.
