I'd love to see the forst suggestion.
Instead of showing "none" it really would be great to show 2 names of the name-generator and then add some kind of occupation or trait like "the Banditleader", "the drunk", "the ever-hungry" or "the whore", so if I click on the parents (or siblings) of a non-story-NPC I see :
Parents: Sorla the beautiful and Peter the mason of Gorn for example.
Would be a cool addition to the immersive fantasies in your head.
