None of those are valid identifiers, see Property talk:P227 for details. GND has "differentiated entries" (Tp) which are valid, and "undifferentiated entries" (Tn) which are *not* valid, as they cover all persons with the same name. As the items are not notable without those identifiers, you might want to delete them instead.
