Many American celebrities have traced their roots and have found a nugget of Irish blood somewhere in their ancestry, at which point they are welcomed by the Irish with open arms and bombarded with invites to visit again soon.
Matthew Broderick, Jeremy Irons and Martin Sheen traced their Irish Ancestors through the program ‘Who do you think you are?’ while other celebrities like Daniel Day Lewis and Olivia Wilde already have their Irish citizenship.
Have a look at the following list of celebs who have been adopted by the Irish people:
Tom Cruise - The hollywood actor, who was recently presented with a Certificate of Irish Heritage by Ireland's Deputy Prime Minister, Eamon Gilmore, has Irish blood on both sides of his parentage. Cruise can trace his Irish roots back to the 12th century and is now an honorary Irishman.
Martin Sheen - Sheen’s mother, Mary-Anne Fieland, came from Borrisokane, in County Tipperary. The actor has a great love of Ireland and has even done a 15-week semester at the National University of Ireland, Galway, where he studied English literature, philosophy and oceanography.
