I can say that Hotari, Kuuluva, and
Jukka are finnish. Actually Kuuluva is not a normal finnish name, just a word...is it "blue"? I can't rmember my finnish skills are very lacking. Aetii might be finnish, not sure...
Danilo is a great name, the name of many people from my country (croatia, and also in serbia)...name of the writer Danilo Kis, too.
