The comedian detailed his experience on PBS' 'Finding Your Roots' during a recent podcast interview
During a conversation on the Connect the Dots podcast, Morgan detailed his upcoming appearance on PBS' genealogy show Finding Your Roots, where a DNA test revealed that the rap legend is actually his third cousin.
"I turn the last page, and guess who's sitting there? Nas. Me and Nas is third cousins on my mom's side," Morgan, 55, revealed during the podcast appearance.
"But me and Esco was always tight before that," he added. "I did a show years ago on Comedy Central called One Mic, that was for Nas' mom that just passed away. So me and Esco always been tight."
Morgan — who is scheduled to appear on the eighth episode of the PBS series' upcoming tenth season, titled "Mean Streets" — revealed that he later called up his longtime pal to share the surprising news.
"When I found out on the West Side Highway, after the show, I called him up and I say, 'Yo Esco,' he said 'What up Trey?' I said, 'Guess what?' He said, 'What?' And I said, 'I just did Finding Your Roots, me and you related,'" Morgan remembered telling Nas, 50.
"He started crying, I started crying. And I said to him, 'If you ever need me, I'm there, cuz.' He said, 'Cuz, if you ever need me I'm there.'"
As Morgan noted, the episode is scheduled to air in February, and he learned a few other facts about his familial history in the process.
"They went back 400 years on my father's side and 400 years on my mother's side," he said. "I thought I was big in my life till I found out what my great, great, great grandmother did. My great, great, great, great, great grandfather's name was Abraham Mack. I know the name of the slave masters who owned us — I got it right here on my phone — and the slave ship."
He continued, "You need to know who you come from before you leave this earth. Know who you are and where you come from. Knowledge itself. I did a lot of crying. And no matter who you are, you're gonna break down."
