Answer 1

You seem to have lost George IV

Answer 2

I would imagine that records verify the Sovereigns of Scotland, but the lineage of earlier kings is otherwise best left to legend.

Answer 3

You need a professor to answer your question.

What is your purpose? The names you list are amusing, so maybe you are having a laugh about hereditary monarchy?

I need more info to help more. Interesting question and good luck, meanwhile.
