I just proposed the merge. There is a wife named Mary Ann who also has a duplicate, but everything else looks in excellent order. You will be able to approve the merge for the one whose trusted list you are on. As to the other one, you need to file an Unresponsive Manager Request. Since you have already made the sufficient attempts to contact the manager and ask to be on the trusted list, it should probably take about a week for your request to go through. When your request is granted, the profile will be orphaned and you will be able to adopt it and complete the merge on that side, as well.
Do you need help with how to file this request?
