I like
Wren on paper. It's cool and individual. But when I hear it said aloud, I realise how insubstantial it sounds. If it were spelt
Ren, I don't think anyone would like it. The 'W' makes it look deceptively interesting, but names are pronounced far more than they are written, and in the end, it is just "ren".
