Great question Mary, if you want to take a person out of your tree you need to remove yourself as profile manager and from the trusted list. From Ashley's profile, click on the privacy tab and then scroll down and click "remove yourself." This should do what you're trying.
Do note that this won't work for profiles of people who are still living. They need a profile manager and you will need tor remain so for the time being.
I hope this answers your question. If not, let us know!
