My sister is a Georgina... the kids call her Gee which she much prefers as she's been George all her life!
I was going to be called Sarah-Jane but while Mum was in labour with me she watched an old black & white movie with a big black housemaid who kept saying Sarah-Jane, Sarah-Jane in a long southern drawl & its put her off (thankfully no offence to any Sarahs) and my Dad came up with Linzi which is also why its spelt in such a random way!
