Since we still haven't known his full name do you think it has a D?? odds are that he has it since he's a brother to two D wielders by fate.
actually what you don't know is that the family doesn't need to have the name D.no he doesn't,he was born to a noble....if his family had the will of d..they would probably be killed by heavenly dragons who visit the city sometimes.
shut up lol.If he didn't have the D he'd be Ace and Luffy's Sister not brother.
