How about "Nine Ten"?

Seriously though, my firstborn got a rather specific name which was (and is) totally fine - it just set us up for some serious brain racking when it came time to come up with another name that wasn't comparatively boring.

I'd suggest something that:

• you can spell when you hear it
• you can pronounce when you read it
• in all the languages that you care about

That narrows things down quite a bit, I've found. It also makes life so much easier for the kid bearing it.
