That's what I think too, but there must be more to it than that. The World Government wanted to cover it up right? So, if the D's really are descended from this kingdom,why wouldn't the World Government have tried to get rid of them? It would only make sense for them to make sure they could maintain absolute power, so they would want to get rid of any potential threat, ie the D's. It's just like how the marines killed off anyone related to Roger. Yet, Garp is a high ranking marine, who turned down a promotion to admiral repeatedly. Like I said, I agree, but it's not quite that clear.
