Azure's kinship to Olaf is questionable, since his lawyer, instead of showing evidence of it, asked for evidence in contrary from whoever doubted Azure to be descendant of Olaf. When Donald and the nephews found what Blue and Sharky believed to be evidence that a Phoenician prince named Hanno and his kin are the real owners of North America, Azure renamed himself Azure Hanno Blue. It can make people think Blue to be a surname Azure gave himself in order to claim to descend from Olaf in the very first place.
