They are peculiar here, in that at a coronation the sovereign may chose an entirely different name from his or her baptismal name. The coronation anointing with oil being seen as a sacramental act. George Vl was one such name changer.

If so mocking him is in as bad taste as mocking anyone with a condition they cannot help, especially in the light of today's knowledge of health issues.
Truth to tell I wasn't keen on the Hanoverians.
