I am awfully sorry, for I have made a terrible mistake,
Her Majesty The Queen is written with a " Z " -> Queen Elizabeth II.
God Save The Queen, ;-)

The E stands for Elizabeth, II - latin: the second and last but not least R stands for Regina whichalso is latin and simply means - Queen .
So the EIIR e.g. in the royal crest means Queen Elizabeth the second.
