I can imagine that when you're yonger thwese things don't get noticed... in our house we all had such names, and so thought little of it... i wasn't unti I was about 14 that people began to comment, in a fairly negitive fashion... I began to use my middle name (which is Tristan) for quite a while after that...
But I dont mind having an "unusual" name anymore...

Twinkle Star is an interesting one though... most of my family are name after mythological characters so seem to have some sort of basis, not sure where "Twinkle Star" could have come from... were her parents maybe hippis? I hear that hippy types often name their children after things, I think quakers do too...
