Who are organization xiii members

Hopefully someone will out these in order but here they are:
Xemnas, Xigbar, Xaldin, Lexaeus, Larxene, Marluxia, Axel, Roxas, Demyx, Vexen, Zexion, Saix, and Luxord, but in KH 358 days/2 Xemnas create a fourteenth (ruining their name, by the way): Xion. This isn't the order of them, so don't pin it on me if it's wrong, because I already know that. But that's the spelling and all of them, just to answer your question. in whatever you're doing!

The Order is Xemnas Xigbar Xaldin Vexen Lexaeus Zexion Saix Axel Demyx Luxord Marluxia Larxene Roxas Xion
