Unlinking FB page from daughters

Are you an administrator on her page? Then just create another FB account and make that the administrator. I'm not really sure what you're asking. Pages have administrators; they aren't the same as personal accounts.

just tell her to eliminate link to your account.

The reason I'm wanting to unlink is because when she posts replies to photographers etc, it shows as posted by Myra Casey instead of her name even though the page itself is listed as her name but it does so because it was set up through my FB account. If I create a FB account in her name I want to be able to link the page we already use instead of losing everything.

You should be able to make anyone an admin on the page that you want to. But of course they have to have an actual FB account first.

Oh and BTW, once you do, there's a way (keep in mind FB moves things all the time so hunt around if I don't give you the exact way your setup is) to, when you are ready to post, to pull down -- usually it's a small arrow to the right of the post -- to post as the page or as yourself.

Nobody else can see the "posted by" except those of you that are attached to the page fyi. That only shows in case there are several people managing the page and there is a question of who did what in the future.
