MP hasn't been active for a while, so you need to do the Unresponsive PM process. When you submit the form, you normally do it from one profile, so you will need to fill in ithe information that you want ancestors and descendants of that profile and any others, if that is what you want done. Maybe they will orphan all of the open profiles. At least some of those profiles are possibly living profiles, so those profiles could be deleted when the Unreponsive form is filled out.
