It is up to each translator/contributor how they want their languages theme to be :)
If a country had a presence in the area its typically a question of using the historical name, but when a country wasn't present translators look at how other colonies were named.
Monarchs? Place names in the old world? Holy people?

For Turkish surely there are place names in the former empire that was founded by Turks that could serve as inspiration for New World colonies, but mostly its a creative role :)

Also, it's considered polite to reach out to the original translator, this will also make the end product higher as you suddenly have someone to spar with :)

Best of luck!

Okay then, i'll do my best and look at german, turkish, french and dutch versions, another question since i haven't tried it. Is there Walloon names as well? If not i'd love to use my creativity with that culture. If i find something that just doesn't make any sense geographical term wise, i will let them know and come to you with the result, thanks for your quick reply.

There's no Walloon names, although I doubt it's been at the top of anyones list lol :p
And please do! :)

Hey, not everyone is worthy of having their imaginery belgium okay? I'll get to it and let you know sire
