May I humbly ask why you want to do this in the first place? My first name is Jan, which is both Dutch, Afrikaans and Polish (and probably exists in a few more languages), but it is an abbreviation of Johan/Johannes/Johannis/Ioannis, which could be Jean in French, Juan in Spanish, Ian in Irish/Scottish, and whatever else. The possible derivations will go down endlessly the further you go down the tree.

Edit: Forgot Afrikaans, sorry Host Country!
