Cavanaugh
An Irish surname from Gaelic personal names meaning “handsome” or “well-shaped,” later anglicized in several spellings.
The #2,049 most common surname in the United States (2010 Census) — about 1 in every 17,565 Americans shares it.
Etymology
Cavanaugh is an Anglicized Irish surname, most commonly traced to Gaelic forms such as Ó Caomhánach or related names built on caomh, meaning “gentle,” “kind,” or “handsome.” In that tradition, the name points back to an ancestor with a personal name or nickname based on the idea of attractiveness or pleasantness. English spellings vary because Irish names were rendered phonetically into English over time.
History
The name is strongly associated with Ireland and Irish diaspora communities, especially in North America. Different families with similar-sounding Gaelic surnames were often standardized to Cavanaugh, Cavanagh, or Kavanagh, so the spelling does not always reveal a single origin line. In the United States the name became familiar through Irish immigration in the 19th century.
