Hi Maggie,
Basically Project Protected Profiles help protect against the adding of or changing of information on the profile without collaboration with the group of which it is a part of. For example the profile of Marie Robichaud is protected by the Acadians Project Your best bet would be to talk with the members of the project and show them the sources you have and collaborate together as to the reliability of the information. You can find out more about the project by clicking the clickable link in the comment.
Best Regards
