And then there's the unusual name spellings that actually aren't unique at all... my DD (19) has a name which is considered to have a unique (ie, made up) spelling - but actually? It's the Portugeuse spelling, and reflects the fact that her paternal grandmother's family is Portugeuse.
Over the years, I've had a lot of abuse for it though - her primary school, for example, practically sneered at the fact that her name has a 'C' and a 'Y' in it, when surely everyone knows that for there to be a 'Y' in her name, then it must begin with a 'K' and not end in an 'E'... (may possibly have just outed her actual name). They did back down when I explained, though. Possibly they were worried I'd call them on their inadvertant racism.
I also have the French spelling of a name which my mother insists was always meant to be pronounced the English way. And an Old English middle name which no one has ever heard of. There's been more than a few raised eyebrows over that one, over the last 40 years or so. I'd drop the extra 'E' and change my middle name... but why should I have to? It's my name. The first gift my parents ever gave me.
My DD and I both like our names. Even if we do have to repeatedly spell them to people who are so insecure in their own lives that they feel the need to try to ridicule and/or sneer at us for them. Little people, narrow minds and all that.
