I have a cousin who my mom and aunt came up with her name. Apparently they hadn't agreed on a spelling though so she ended up having two different ways of spelling it growing up. Later on when she turned 18 she ended up using neither one of the spellings that they had chosen.

Then there is my name which is common in the UK but not the US so everyone here spells it wrong and/or mispronounces it. It is bad enough that I just ignore it and will only correct someone once or twice before just taking it as whatever they decide to call me.
