Forum:KB:Tavion "Axmis"...

In the article on Tavion from the Jedi Knight series, she is named "Tavion Axmis". Most of the times she's mentioned by name in the article, she's simply called "Axmis", despite the fact that she didn't seem to have a surname in either Jedi Outcast or Jedi Academy.

This may or may not be the place to ask, but I have two questions: (1) How do we know about her surname? (2) Wouldn't it be smarter to refer to her less-obscure first name? When I first read the article on Jedi Outcast, I kept getting confused about who "Axmis" was.
