Unusual Names

I just saw a tv presenter whose name was Chelsee. Very unique name, as many are these days. Every man, woman and child is unique, we are all different. It occured to me that this lady called Chelsee has to spell her name to almost every single person in her life who asks, as it is not the norm. How many people will make the mistake of writing it incorrectly? My wife has an unusual name (french) and for over 30 years even family get it wrong. All children are special (they must be coming from us) but are we burdening them by naming them an unusual name?
