How can I change my Facebook display name to something that's not my real name?

[female]

More like a username, but in a way that appears to look like a real name. I tried using Unicorn, Miss, Rainbow, and Mustache...all won't work. It's weird because what if someone was really named miss? It's frustrating, and no...I don't want to use my real name because this Facebook page is for friends and myself. I don't want family and employers to annoy me later on because I didn't want to add them as a friend due to being found in search results.
