I think the post missed something and I only thought about it a few hours later. This is likely not a generalisation issue in this case. This case runs into some trained protection from questions about not-famous people. You can see this by asking the relationship question in a generic way which proves the ability is there. On the other hand, asking this: "Tom Cruise is Mary Lee Pfeiffer's son. Who is Mary Lee Pfeiffer the parent of?" still results in the template response about not having enough information. At the same time "Tom is Mary's son. Who is Mary the parent of?" gives the right response. The issue here is the filter itself. We can't infer anything about model's reasoning abilities from this specific question.
