A few comments on the Scandinavian names:
Netherlands is not a part of Scandinavia, so the dutch names doesn't belong in that group.
The comments in the file says "Please do not use "...son" or "...dottir" as a family name yet, they are male/female-spezific". This is wrong. In modern Scandinavia names like Nilssen/Nilsson are not gender specific, and the dottir ending is generally not used. The exception is Iceland, but Iceland are usually not considered a part of Scandinavia. So I suggest that they are included again, preferably with a mix of ..son (Swedish) and ..sen (Norwegian/Danish) endings.
Soeren should be spelled Søren.
