Actually, now that I look, it seems his last name has only been given (as "Sand") once in the manga in chapter 59 (I was confused since, when GodKingReiss last edited Marlo's page, he mentioned that Marlo had been referred to as Sand again in volume 15, making me think that the name had been referenced again; but chapter 59 is in volume 15... So long story short, the name has only been used once and I'm an idiot :D ).
