Just for a bit of fun as I'm all out of ideas for my DS to be! Started thinking about it and I actually love lots of names that are usually short for something, e.g. Jamie, Ollie, etc. But not using the "full name", just the shortened version on the birth certificate. Never really understood why people have the full name but then only call their kid by the short version. But each to their own 
Can you think of any more that could stand alone?
