They don't have to be. If you find the name of some thunder demon scrambled up in Larxene's name, it's pretty obvious what her name is I don't think SE would have something like that hidden if the name was something different. I suppose I should have clarified or perhaps said more about the six apprentices' names being real names because there are few names that are all elemental. I would though be more inclined to believe a name as true if it related to the element.Only two of the names do, and they're not even confirmed. x.X
