Since people seem to not want to recognize the significant Norwegian/Danish Viking input in Ireland (which is present in every region of Ireland) and the English input in the country which comes with Anglo-Saxon admixture and Celtic both, I think it is necessary for us to point out many Irish do look passable in Scandinavia and Germany.

Niall Horan from One Direction is a good example of this. He looks as Scandinavian as it gets.
