I think it's even funnier when the parents name a kid something so common, and then as a last ditch effort to make them unique, and they change the spelling. Like Katie or Katey to Katea, or not even try and name them the automatic obligatory first 3 guy names. Zack, Micheal, or Kyle. Girls is Emily, Samantha, and Megan. The scourge of Emily runs rampant in my school.
Names go through cycles, in different countries. What is popular one decade is unpopular the next because nobody wants to be reminded of their grandparents names. For instance, I've never met anybody called Megn of any age, and all Emilys are either really old or really young. I've only ever known one Samantha but Catherine is quite popular among people my age, though rarely any older people. Never met a Kyle and only one Zack.
Even the traditional names go through cycles, in the seventies, it was the new Tetstament names, Mark Luke, John, Stephen, for my generation, a lot of the old testament names are more popular. Joshua, Adam, etc.
