Well, far as I know, there are three traditional Igbo kingdoms in Nigeria and, if you are willing to dig back enough, you are surely related to some dynasty.
I mean, number of direct ancestors is geometrically increasing according to the number of generations... So if you go back, let's say, forty generations back (that's cca. 1000 years, not that much of time) the number of your ancestors would be 1 099 511 627 776 - which is more than the total number of humans who ever lived on the earth.
So yeah, statistically, everyone's for sure related to some royalty. Not that it matters. It's just an interesting piece of trivia.
As for the rest, I really don't think conscious brothas need to have such an inferiority complex.
