Wrexon sounds quite North England, I'll go with Draxon as a Southern version!
I like the name Tree, it's not a made up word, but I'm fairly sure it's not a name, not that I'd ever have the guts to use it for real but I once met a guy called Trevor, who was just too cool to be Trevor and i nicknamed him Tree in my head.
For a girl, maybe Esher, like MC Esher the artist, I always thought it had a nice sound to it
