I'm surprised at the response to
Nell, at best it seems nicknamey to me, at worst, it reminds me of death knell lol, I think I've been reading too much Shakespeare.
I'm really glad to see
Muriel, I agree it has a frumpy image, but underneath that it's such a pretty name and hopefully if you start to see more girls called
Muriel it will lose the image.
Jamie is not as unisex here, it is quite firmly established as a boys name (my dad is known as
Jamie) and girls called
Jamie are very much a recent phenomenon, and still in a minority.
