As for the origins of the name, I can't help you there. However, if you're wondering why Amy uses Amy Lee as her stage name, here's why: Amy Lee is her real name - she was born Amy Lynn Lee, but decided to keep her middle name out of her stage name. She is now married and is called Amy Lee Hartzler, but she decided to keep her stage name as Amy Lee.
Amy Lynn Hartzler is her married name. Amy Lynn Lee was her full name before she was married. It isn't fake.
