Ilmarinen

There's no way in hell anyone would ever name their son this in Finland. This name is only associated with the character in Kalevala, and you'd have to be insane to use this pompous name on a child. I doubt it would even be legal here! Besides, this name sounds more like a surname than a first name anyway. Many, many Finnish surnames end in -nen, and many end in -inen and -rinen as well, so I really do believe it actually isn't even legal. No sane Finn would name their child a surname, or a name that sounds just like one.
