What's in a name?

I've just been reading this http://timesonline.typepad.com/alphamummy/2008/07/20-strangest-ba.html about weird names. I've come across Teresa Green and Arran Cardie but nothing else terribly notable. I knew of someone who called her children both girls Ocean and Summer which is hardly remarkable today. I also worked with a girl who was always known as Gina but was actually Georgiana and her sister was Xanthe. I also worked with a woman called Isora though she was always known as Is. Everyone thought her parents made a mistake and it should have been Isadora.
