Stephen – Hungary
There is a list of accepted names in Hungary that are derived from the local tongue. This indicates that whereas Stephen is prohibited, Stefán is permitted.
Parents may make requests to have their children’s original or foreign names added to the registry, but they must use the Hungarian orthography when doing so.
For instance, you would need to write Juliette as Zsüliett if you wished to name your child Juliette.
Messi – Rosario, Argentina
Lionel Messi, a footballer for Barcelona, hails from the Argentine city of Rosario, where so many infants were given his name that a law was established specifically outlawing it. As a result, Rosario parents are no longer permitted to legally give their kids the name “Messi.”
