I actually agree with Lumia too. I am more than comfortable to find an english name and use that as a unisex name. BUT with Emlyn it was a different case. The name is strictly Welsh and seeing as we travel there every 5 or so years I thought, what happens if my daughter Emlyn turns 20 and decides she wants to live in wales for a few years (like I did when I was in my 20's)... what would the locals opinions of her name be and would she have to discover a way to handle retorts that she wouldn't have discovered back here in Australia?!
While in general I agree that the naming of a child is the parents right and I actually was offended when my mum said "thats an awful choice for a girl"... I think there are some exceptions where you need to consider cultural and social context.
