Not that I have seen!
I actually changed my name (by deed poll) @ 20 years old.
First, Middle and Surname. Not that I had something completely new though!
I had a double barrelled first name a long middle name and a double barrelled surname that now didn't actually contain any of my parents surnames. (My mum married my step dad and my dad 'uses' more than one surname, he wasn't using his real one when he was with my mum.)
The first part of my first name was hardly used by anyone, and when it was first used by someone I didnt know they would always get it wrong. Plus I had a nn from it I would have preferred not to have. So my first name is now just the second part of my old first name.
I completely changed my middle name as I didn't really like it and already answered to a different name by some family members who think I look like someone famous with that name (I do sometimes see that on here).
My surname is now my stepdads. Suits me much more and people always said that I have the traits of a 'S......' rather than traits from my Mum or Dads side, lol!
I do now find that when registering somewhere I have the need to explain my name change!
Phew that took a while to type.
I am happy to give names if people are interested?
