'Sabin' is a rare name, but a real one nonetheless. It's feminine form, 'Sabine', is still popular in Europe though. I'm glad it was changed. How many royals would name their twin baby boys Edgar and Mash? I can just imagine it...

Queen Figaro: "Oh, what a beautiful child! What should we call him?"

King Figaro: "Why not call him 'Mash'? After all, he might want to be a martial artist when he grows up, then he'll be able to 'mash' anyone he doesn't like!"

By that same logic, they could've called Edgar 'Pointy Object', for many reasons.
