Perhaps whoever entered him, didn't know WHO the father was? Or do you know in fact that this profile HAD a father which is now missing? I can find no record of this profile being disconnected from any parents.

It looks like the old error when a plain merge causes parent connections to get lost. It happened me two times for some days ago and have reported the error.
The tree revision for this specific profile shows who was connected as parents, so it is just to reconnect.
