I think the most well-known Unity is Unity Valkyrie Mitford... the Mitford sister who thought Hitler was a pinup, and tried to kill herself when war was declared between her countries, as she thought of them.

A good friend of ours is called Thalia, but for the Greek, not AF! Her parents are conservative Afrikaans people, so she is generally happy that she didn't get a weird combination name, or even more peculiar inherited name (Jomar/Glodina/Sugnette/etc.)
