O'Rourke
A classic Irish surname meaning “descendant of Ruarc,” a personal name associated with a famous medieval Gaelic dynasty.
The #2,213 most common surname in the United States (2010 Census) — about 1 in every 18,761 Americans shares it.
Etymology
O'Rourke is the Anglicized form of Irish Ó Ruairc, meaning “descendant of Ruairc.” The personal name Ruairc is generally understood as a Gaelic form related to the older name Ruarc, traditionally associated with strength or notable rule, though early writers sometimes glossed it more loosely. In English records the name appears in several spellings, including O'Rorke, Roarke, and Roark.
History
The name is strongly associated with the medieval and early modern O'Rourke lordship of Breifne in Ireland, where the family was prominent for centuries. After anglicization, many bearers dropped the apostrophe or simplified the spelling, which helped produce modern forms such as Rourke and Roark. The surname also traveled widely through Irish emigration, especially in the 19th and 20th centuries.
