I changed my first name because of issues with it. It wasn't a dramatic change at all, I removed a hyphen (-) and made it easier to pronounce.
My name was Anna-Marie and is now Annemarie. Since childhood, I've gone by Anna, except when I was in trouble. I always got "Anna Maria" or "Anne Marie" and the hyphen caused problems more often than not. I don't know why my parents added that in.
Anyway, I hated my name, but I've come to terms with it. I learned the history of it; it's a mixture of family names. I do hate my middle name and I never use it.
