"I'm not sure how to merge her into one."
The member tree program has a merge duplicate function (see below).
Before merging, check for 3X grammy in the "List of All People" view. Do this in another browser tab.
In this view, you can confirm how many profiles you have for each individual, you should only have one profile per person.
To merge duplicate (or more) profiles of the same person, go to one of the profile pages of the person. On the profile page, pull down the *More Options" menu and select "Merge with Duplicate".
Most users find working with several tabs open to their tree makes the process less confusing and easier. You always need to refresh the other tab pages when a change is made on another tab page. This insures the changes will be reflected.
