Cearbhall m
Irish Gaelic: name of uncertain derivation; it possibly arose as a nickname for a violent warrior, from cearbh hacking. In the Middle Ages it was common among the learned Ó Dálaigh family of traditional poets. In modern times, it has been borne by Cearbhall Ó Dálaigh (1911–78), president of the Irish Republic.
Variant: Cearúl(l) (a modern ‘reformed’ spelling).
