What are some of the most multicultural names you can think of? What parts of the world are they used in? They don’t have to be spelled/pronounced the same everywhere they’re used–names with many variants are welcome.
I love the idea of a little citizen of the world who can travel anywhere and have a name that fits right in!
You mean names that work in lots of places/languages? I can think of a bunch, they tend to be pretty short and simple.
[name]Ana[/name]/[name]Anna[/name]
[name]Lena[/name]/[name]Lina[/name]
[name]Maya[/name]/[name]Maia[/name]/[name]May[/name]/[name]Mae[/name]/[name]Mei[/name]
[name]Sara[/name]/[name]Sarah[/name]/[name]Sarra[/name]/[name]Sora[/name]/[name]Sari[/name]
[name]June[/name]/Joon/[name]Jun[/name]
[name]Rona[/name]
[name]Emma[/name]/[name]Ema[/name]/[name]Emmy[/name]/[name]Emi[/name]
[name]Dara[/name]
Boys are harder for some reason, but…
[name]Sam[/name]
[name]Amir[/name]
[name]Neil[/name]/[name]Niall[/name]/[name]Neel[/name]/Nail
[name]Omar[/name]
[name]Kai[/name]
[name]Ken[/name]
[name]Anita[/name] (used in Southern Europe and South [name]Asia[/name])
[name]Lila[/name]/[name]Leila[/name]
[name]Matthias[/name]
[name]Elias[/name]
[name]Roy[/name] (Used in English speaking countries and South [name]Asia[/name])
[name]Laura[/name] is used around the world
[name]Yosef[/name]/[name]Josef[/name] fits pretty much anywhere with an Abrahamic population, [name]Christian[/name]/Muslim/Jewish. There’s usually a form of [name]John[/name] as well but [name]John[/name] seems to vary more, y/j issues and [name]Yosef[/name]/[name]Yusuf[/name]/[name]Yousef[/name] transliterations aside, [name]Joseph[/name] is pretty consistent.
For girls, one of my favourites is [name]Reina[/name]/[name]Rayna[/name]/[name]Raina[/name]. (all often pronounced rain-uh) It is used in a number of Latin-influenced languages ranging from Spanish through Bulgarian as a form of [name]Regina[/name], in Yiddish as a form of [name]Katerina[/name], and in Japanese with its meaning varying depending on the way its rendered.
The similar [name]Rina[/name]/[name]Reena[/name] is shared (with different meanings) across many languages including Italian, Dutch, Hebrew, Sanskrit, Hindi and Japanese.
[name]Nina[/name]'s about as multicultural as you get for a girls name. 
I agree with pp’s, [name]Anna[/name], [name]Maya[/name] and [name]Sarah[/name] are all easy to find really similar names around the world with varied spellings.
My name is [name]Sara[/name], and it works in all of Europe, Arabic countries and Spanish.
Agree. [name]Nina[/name] travels beautifully.
I’d add [name]Milena[/name], [name]Maria[/name] & [name]Amara[/name], the vowel-cons-vowel pattern tends to translate easiest in my observation.
[name]Amaya[/name] was one I ran across yesterday.
I love [name]Reina[/name] and [name]Nina[/name], I think they would both work very well! [name]Milena[/name] too, it’s gorgeous.
[name]Anita[/name]
Scandinavian, Southern Europe, South [name]Asia[/name]
I’m a [name]Lucia[/name] and had no trouble travelling or living abroad with it (or any troubles with it at home, though I go by [name]Lucy[/name] most of the time here). I think it travels very well and I’ve been happy to have it.
[name]Iris[/name] travels decently too, I think.
I’m not so sure for boys, though… [name]Daniel[/name]?
[name]Maria[/name]! Definitely can be used in several countries, if not most.
