You also see this quirk with certain NPCs using titles over their actual surnames. Particularly amoung Elezan (Aymeric the Blue, Haurchefant Greystone, Alaimbert of the Spiked Butt), but not exclusively (Franz the Fair).

I recall Pipin was shown with such a name in one instance, but I'm frustrated now since I can't a picture of it!
