* NN is the Latin abbreviation for "nomen nescion" or "non nominandus" meaning "name is not known" which is a standard across Europe for genealogy, newspaper reports and court affairs. This is more language neutral and globally acceptable than using the English terms "Miss", "son" or "daughter" in place of an unknown given name. It is also preferable than leaving the given name blank, as it clearly indicates the name is missing.
