Saoirse Una Ronan (born 12 April 1994) is an Irish film actress. She began her career as a child and came to international prominence in 2007 after co-starring in the film Atonement, which gained her nominations for a BAFTA, a Golden Globe and an Academy Award for Best Supporting Actress.
Ronan has since appeared in several Hollywood films, including the children's Christmas story The Christmas Miracle of Jonathan Toomey (2007), with Tom Berenger and Joely Richardson, the romantic comedy I Could Never Be Your Woman (2007), the film adaptation of the science fantasy Young Adult novel City of Ember (2008), Death Defying Acts (2008), the war drama film The Way Back (2010) and Hanna (2011). She was awarded a Saturn Award and a second BAFTA Award nomination for her portrayal in Peter Jackson's The Lovely Bones (2009).
Born in New York City, Ronan is the only child of Irish parents Monica and Paul Ronan – the latter an actor – who were living in New York at the time. She was raised in County Carlow, Ireland, having moved there when she was three years old. Ronan is currently home schooled and lives in County Carlow. As a baby, she sometimes accompanied her father on the set when he was working on such films as The Devil's Own.
Ronan supports the Irish Blue Cross, as the charity had reunited her with her runaway dog Sassie. On her name, she said, "'Searsha' is how Irish people pronounce my first name, but I would pronounce it 'Sersha,' like 'inertia'. It's Irish for 'freedom.' I recently found out that my middle name, Una, means 'unity' in Ireland. And I think my last name means 'seal.' So I’m a free, unified seal."
