As you well know, today is St. Patrick’s Day. But if you’re not consciously aware of any Irish ancestors in your family tree, you may find yourself feeling a little left out of the festivities. Well don’t worry. There may be some Irish blood lurking in there after all. Here’s a list of people who, surprisingly… and not so surprisingly, have Irish ancestors. So use these celebs as hope that one day you may be able to celebrate the “green day” with full conviction.

Everybody and their mama has seen “Roots” (basically) and many have also read Alex Haley’s book that served as the basis for the record-breaking TV mini-series. Now e-book lovers will get to indulge in the classic with a few extras.

Check out what the Grio has to say about it:

“Roots is more than a story of one African-American family; it’s the story of our collective history and ultimately it’s the story of America,” says theGrio’s own David A. Wilson in his video intro to Roots: The Enhanced Edition, available now on the iPad and coming to the Kindle, Nook and other digital forms soon.

In his impassioned written introduction, also found in the enhanced edition, Michael Eric Dyson expounds on that sentiment. “From the very beginning,” he writes, “Alex Haley’s Roots counted as much more than a mere book. It tapped deeply into the black American hunger for an African ancestral home that had been savaged by centuries of slavery and racial dislocation.”

Find out more about the extras in the new e-book over on the Grio! It’s a must-read for genealogy buffs and African American culture enthusiasts!
