Hi, Matthew, and welcome to WikiTree. At WikiTree no one owns profiles but you can either be on the Trusted List or a Profile Manager. Have you made a request to be on the Trusted List via a request made from the Privacy tab? If so and there is no response, make your request as a Comment directly on the profile and also on the profile page of each profile manager (I see two of them on this profile). As a family member, the courteous thing for the PMs to do is add you to the Trusted List but they are not obligated to make you a Profile Manager. I see that both profile managers are active on WikiTree. If they simply don't respond to you within a week, post back here and someone will assist you further.
