Hijacked ancestor records due to bad merging
I have a problem with one of my records being 'hijacked' continuously within Family Search. I have created a record for my GGGrandfather more than once but a similarity to another individual with a nearly identical name and wife. Other well intentioned, but unfortunately misguided, users are merging the two individuals incorrectly and since my relative is the lesser known of the two I am in a position where I can't stop it from occurring. Is there a way for the Moderators, or someone with some authority, to step in and either lock, or protect, an individual from future changes? Should I establish a Case?
