The great actresses of Hollywood come from all over the world- some of the best from the ole’ Emerald Isle. You may not have known, for example, that Olivia Wilde’s father Andrew Cockburn was raised in Ireland. That noble lineage came in handy when she starred in NBC’s drama “The Black Donnelly’s,” about an Irish family. Another starlet of Irish decent is Katherine Heigl, whose role as Dr. Isobel in “Grey’s Anatomy” made her famous. See the full list below.
