ChatGPT is able to name other living Rothschild's, including another one named David, specifically David René de Rothschild, but somehow breaks on this particular one. If I ask it to list all living Rothschilds, it breaks when it comes to David Mayer, but if I ask it to name all Rothschilds that don't have the first name David, it doesn't break. So it's able to access the info about David Mayer, but unable to output anything related to it.
