Hello,

It's not possible to "delete" a gamertag. It will always stay there, if you want to close a Windows Live ID you should be able to do this
here, but again that would close everything tied to the service, your gamertag would still be there but now in limbo. It's highly recommended that if you ever want to access
this gamertag again, you change the e-mail associated with the gamertag by following the directions
here.

Hassassinade has good advise here.

The issue here seem to be regarding the use of the child's account in relation to the parent account. Do you both have MS accounts? Are they related as child and parent account? Did you purchased the game on the MS store?
