If you want to make the name change yourself, Sheri, you will should send a trusted list request to the profile manager.
If you don't want to be on the profile's trusted list, send the manager a private message detailing your sources for the name change. You should also post a public comment on Mary's profile regarding her correct Last Name at Birth.
If you don't hear from the profile manager or see that the Last Name at Birth has been changed within a reasonable time period (30 days or so), then you may want to submit the Unresponsive Profile Manager Request Form to have the profile orphaned; you would then be able to adopt the profile to make the change. If you don't want to remain as profile manager, you can remove yourself as manager on the profile's Privacy page.
