Will Ferrell

Will Ferrell is regarded as one of Hollywood’s genuine good guys and one of the funniest comedic actors of his generation. Ferrell has Irish roots in County Longford where his family emigrated from and changed the spelling of their last name from Farrell.

“I’m committed to my Irish roots. James Joyce spent a lot of his time living outside of Ireland, I too have spent a lot of time living outside of Ireland. But it doesn’t make me any less Irish. I’m so committed in fact that I will continue to drive on the left-hand side of the road. Will it be dangerous? Yes. Is it illegal? Highly. But that is how committed I am.”

Both my grandmothers are from Ireland and I have spent every summer in Bantry since my father, who is an artist, had the romantic idea 20 years ago to buy an old farmhouse on the west coast and renovate it.”
