I found three Finnish names at a rather bad baby name page (BabyNamesWorld.com). At least they are said to be Finnish, but are they really? Aila - light-bearer I know this means "halo around the moon" in Turkish, but Turkish is, as you know, not related to Finnish Mika - new moon Isn't it a nn for Mikael? Preita - most loving one I've never even heard this name! Isn't love something like "rakasta"?
One more thing: I know you're an expert at European languages - do you have a clue about the origin of the name Kahlo, as in Frida Kahlo (my idol, heh, heh). It may be German, Hungarian or Yiddish.
