Ó Ciardha

Ó Ciardha is an Irish Gaelic surname, originally a patronymic meaning "descendant of Ciardha." It is most commonly anglicized as Carey, also appearing as Keary, Kearey, Carry, or O'Carry. The name is principally associated with the midland region of Ireland (Leinster), particularly with the historic territory of Carbury in modern County Kildare.

Etymology

The root of Ó Ciardha is the Old Irish personal name Ciardha, a byname derived from ciar meaning "black" or "dark." This likely referenced dark hair or complexion. The surname thus would have originally described a descendant of a dark-featured person. The similar surnames Ó Ciaráin (Munster) and Ó Céirín (Connacht and Munster) were also anglicized as Carey, but share the same root meaning.

Historical Background

One of the principal septs of Ó Ciardha was the ruling family of Carbury, a territory in present-day County Kildare. The Irish annals record powerful members of this lineage as early as the 10th century. For instance, the Annals of Ulster for 954 AD mention "ua Ciardai, ri Cairpri" (O'Carey, king of Carbury), and the Annals of Tigernach note a similar entry for 993 AD. This demonstrates that the family held regional lordship in early medieval Ireland.

Anglicization and Variants

Following English administrative measures in Ireland, surnames were often phonetically anglicized. Ó Ciardha became primarily Carey, though spellings like Cary, Keary, or Kearey also emerged. A large number of Careys today can trace their roots from this line, but not all—the same anglicized form was used for unrelated families. This makes it important for historical research to link Careys with the original Gaelic sept.

Related Names

The surname is closely related to the personal name Ciardha, from which it derives; other eventual Anglicizations such as Cary are also recognized as variants.
