My 3 kids have very ordinary first names that were deliberately picked so they couldn't be shortened. They all have more exotic middle names. We did this so that if they wanted a more unusual first name when they were older, they could use their middle names.
Mr O has FOUR christian names - his mother had delusions of grandeur.
My mum was convinced she was expecting a boy and when I was born she had no girls names in mind. There were 2 other baby girls on the ward and, having no imagination, she named me after them. It's lucky for me there were other babies on the ward. If mum had been alone and looked around for inspiration, I could have been christened Wash Handbasin or No Smoking!
