My real name is a Greek mouthful, commonly misspelt and mispronounced. I have never liked it. I also have no idea whatsoever why parents chose it (no precedent in the family and no-one's Greek either!) and they've never called me by the full version!
So for my daughter I wanted a name that was easy to spell and pronounce, and at the same time not too run of the mill yet not too esoteric. I would have like to call her Harriet (a family name that would have made my dad v happy ) but my partner was having none of that. So she's Hannah - I still like her name and she does too.
Strangely, virtually no-one in my entire family has ever been known by their given name but only one changed their name by deedpoll, when the man who would have been Norman changed to Tim!
