Issymum - my friend's middle name is Aneurin, and his brother calls him Anadin! but he was named after Aneurin Bevan.
when my niece was born, and SIL called her Daisy, the whole family thought it was odd (this was just before it became fashionable, we reckon she started the trend!), but now you just couldn't imagine her being called anything else, and think it's lovely.
as a Registrar, I have practised my 'oh, how unusual' face and think I'm quite good at not snorting now! we get lots named after places their parents went to on honeymoon, luckily they've all been quite exotic, can you imagine being called 'Skegness' which is my parents went!! also had one that was being adopted and mum gave him an absolutely awful name that would guarantee him being picked on, saying 'well it'll be changed anyway, so thought I'd have a laugh'. I didn't know whether to cry or thump her - what a cow!
