Angela Davis was shocked to learn that her ancestors came to America on the Mayflower, making her descendants of people who helped found the country.

The civil rights activist learned about this news during the Feb. 21 episode of PBS’s Finding Your Roots with Henry Louis Gates, Jr. Gates shows her a manifest of names, eventually revealing that the document had the names of the Mayflower passengers.

“No, I can’t believe this,” she said, laughing through her surprise. “My ancestors did not come here on the Mayflower.”

When asked how she felt about the news, Davis said, “…That’s a little bit too much to deal with right now.”
