Kavanagh
An Irish surname from Gaelic roots, traditionally linked to a byname meaning “mild” or “gentle,” and also associated with the medieval Kavanagh dynasty of Leinster.
The #6,414 most common surname in the United States (2010 Census) — about 1 in every 58,243 Americans shares it.
Etymology
Kavanagh is the anglicized form of Irish Gaelic Ó Caomhánach / Cavanagh-type forms. The older scholarship in the supplied sources connects it with caomh, meaning “gentle,” “mild,” or “kind,” giving the sense of “the gentle one” or “descendant of Caomhánach.” Another traditional explanation ties the name to a fosterage story: Donnell Cavanagh was said to have been given the nickname because he was fostered by the coarb of St. Cavan at Kilcavan in County Wexford.
History
The name is strongly associated with Leinster, especially County Wexford, where the medieval Kavanagh (Caomhánach) family became a notable Irish lordly line. In modern records it appears in several spellings, including Cavanagh and Kevan/Keaveny-related forms, reflecting anglicization and regional pronunciation. It remains a common Irish surname in Ireland and in the Irish diaspora, including the United States.
