My sign in name not my gamertag PLEASE HELP ASAP

Everytime i sign in on xbox live the kinect recognizes me as my sister and It is because i took her gamertag and made it my own because she no longer plays xbox. How do i get the xbox to change the actual name? i tried to go into my accont info but nothing shows up?
