I hate my given name. I don't identify with it and stopped using it to all intents and purposes a long time ago. I use my middle name but I can't say I like it much better. Both names are too girly sounding; the first one is way too popular and on top of that it's spelled in a less common way; it's not a made-up spelling, just lesser used, so folks are constantly mis-saying it for some reason, even though when I worked at school a 10 year old child rightly pronounced it from reading my name tag and this was a girl who was basically illiterate and had a tonne of trouble reading.
My eldest is not at all girly, but her name is basically unisex, and she seems fine with it.
But we did spell it in a less-common (but not made up) way, and I do worry that will drive her nuts now.
Even worse, with this next baby coming, my wife and I agreed on a girl's name we both like, but we both assumed a different spelling. I'm not sure there is a commonly agreed 'normal' spelling for it.
