Nas appeared on an episode of PBS’s Finding Your Roots, where he traced his family tree back to his enslaved ancestors.

In the clip, the rapper is presented with a bill of sale for his third great grandmother, known as Pocahontas, back in 1859 for $830. “They paid $830 for my great, great, great, grandma?” Nas says to host Henry Louis Gates. “I got more than that in my pocket right now.”
