You really do want David Hughes to be Welsh don’t you!  Yes you’re quite right that he was proud of his Welsh ancestry, and even sort to use this as a way of promoting himself as a singer.  But your original argument was that being born in England did not define his nationality and that because of his Welsh parentage he was Welsh.  I see you have even added new Welsh categories to the article in accordance with your view that he was Welsh.  The only thing is it still remains that his parentage was only half Welsh, and surely because he was born and bred in England rather than in Wales this would have implications for his nationality.  Maybe something like ‘an English-born popular singer of Welsh extraction’ would be one way of getting round things?  (  )
