*Nas will be among the new crop of celebrities presented with their family history in the PBS series “Finding Your Roots” — and the first rapper to ever appear on the program, which begins its second season in September.

“We introduced Nas to five generations – we’ve never been able to do this before for any African American – five generations of his enslaved ancestors,” said the show’s host Dr. Henry Louis Gates, Jr. during a TCA panel Wednesday morning.

Researchers also unearthed an actual 1859 bill of sale for his third great grandmother whose name was Pocahontas Little. It’s a document Gates referred to as “extremely rare, something we’d never seen before.”

Upon seeing the document, Nas told reporters, “I had to stop and deal with that for a moment. This is a sale of a human being. This was business here in this country.”

Nas says he was initially “enraged” at the bill of sale: “I was like, that guy that owned property owes me some cash. My people made him really wealthy, so maybe I should find his family and talk.”
