Two years later, and no one has supplied an answer. Maybe it's time to disconnect those parents, based on Anderson's information (which is now on the profile).
When that profile was created, an Ancestry File Number was added. To see what information the contributor was relying on, I checked that AFN on the familysearch site and got no results; not surprising, since the format doesn't look like a valid AFN.
To make one more try at getting an answer, I've sent the contributor a PM asking if he recalls his basis for making that connection.
