What's in a name?
In Switzerland there used to be restrictions on what first name you can give your children.
My parents wanted to call me Taliesin, which was not allowed. So, I was born Alexander Talesin. Later, a name change was made to rename me to Taliesin Alexander. The Australian authorities know me based on my birth certificate. So in Australia I am Alexander and in Switzerland I am Taliesin.
Just to make it more interesting, if you pay close attention you'll notice that my name was misspelled when I was born. This caused a lot of confusion for several banks and government agencies. My favorite part about this is how diligently people will follow what their screen tells them. If a computer tells you that I don’t exist, then who am I to argue?
So far, I’ve been allowed to continue not-existing.
