Girl name · 48 babies recorded · 1974–2025

Oonagh: 48 babies born in Scotland since 1974, given to girls, peaking at 6 births in 2019.

Oonagh is the Irish and Scottish Gaelic form of the name Úna, derived from the word for “lamb,” though it is also sometimes linked to the Latin "una," meaning “one.” The name carries a gentle, pastoral quality. Notable bearers include Oonagh Keogh, the Irish aviator who became the world’s first licensed female pilot, and Oonagh O’Hagan, a Scottish actress known for stage and screen work. While no major places share the name directly, the variant Oona is famously associated with Oona Chaplin, the actress and granddaughter of Charlie Chaplin. In Scotland, Oonagh has been a consistently used choice, often chosen for its lyrical sound and Celtic heritage, and it remains a distinctive alternative to the more common Una or Oona.
