Unique Girls Names...? Please Answer?

Of the ones you've listed, I like Avonell the best--it sounds like it's spelled, for the most part. With the others, I'm concerned that you may be sentencing the girl to a lifetime of spelling her name--which would reflect back on your decision-making. Find a good balance between uniqueness and simplicity. Eventually, the little girl will be 44, and she may tire of spelling her name over and over again, and feel some resentment.
