I think we sometimes forget WHY we name a person?!
We name him/her so that he/she can be identified as uniquely as possible. Being one of four Lilys or five Jacks (or Evie, Harry or other super popular name) doesn't excactly do that - they need to add a modifier (surname initial or other adjective) to be identified.
There are 1000s of lovely names out there - lets make some use of them!
