John Cusack’s Irish Family Tree

John Cusack can trace his roots back to Ireland on both sides of his family. In fact, all 16 of his great-great-grandparents come from Irish lineage. When he visited Ireland to attend the Belfast Film Festival, researchers commissioned a genealogy report for him to share more about his family’s lineage. 

The actor had heard from his parents that his father’s family was from Meath, while his mother’s side was from Galway. However, the commissioned report showed that this was the reverse.
