Thankyou so much to everyone for your responses....they have been very helpful!

Ali - DH loves that your neice and nephew are named Henry & Charlotte!
KT I think you might be right re having too many choices when it comes to my indecisivness!
Shar - If it's a girl and we call her Charlotte, we were going to use 'Charlie' day to day already!

Thanks everyone for the suggestions, some of them are no's for various reasons (close friends names, nieces names etc) but it's all good food for thought!

Hopefully I will stop over thinking this and start obsessing about something else!! LOL!
