"Turris Fortis Mihi Deus"

Kelly (Ó Ceallaigh )

The Kelly family, originating in ancient Ireland, is one of the most prominent and widespread Irish families. Known in Gaelic as Ó Ceallaigh, the family has a rich history of leadership, scholarship, and cultural contributions. They played significant roles in Ireland’s medieval period, particularly in the provinces of Connacht, Leinster, and Ulster.

Surname Derivation

The surname Ó Ceallaigh translates to “descendant of Ceallach.” The personal name Ceallach is believed to derive from the Gaelic words ceall, meaning “church” or “monastery,” and ach, a suffix meaning “pertaining to,” or from ceall, meaning “bright-headed” or “warrior.” The name suggests a connection to either religious devotion or warrior prowess. Over time, Ó Ceallaigh became anglicized to various forms, including Kelly, Kelley, and O’Kelly, making it one of the most common surnames in Ireland.

Origins & Ancestry

The most notable branch of the Kelly family hailed from the kingdom of Uí Maine (Hy Many) in present-day counties Galway and Roscommon. They claimed descent from Máine Mór, a semi-legendary figure who established the kingdom around the 4th century AD. The O’Kellys of Uí Maine were prominent chieftains and held significant power in Connacht. They were known for their resistance against Norman invasion and for fostering Irish culture and education.

Famous Ancestors:

• Tadhg Mór Ó Ceallaigh: A 10th-century king noted for his defense of Uí Maine against Viking raids.

• William O’Kelly: 14th-century lord who patronized the arts and commissioned the Book of Ui Maine, an important Gaelic manuscript.

Leinster Branch - Breagh

Another branch of the Kelly family originated in Breagh, an ancient kingdom in modern-day County Meath. This lineage traced back to the southern Uí Néill, descendants of the legendary High King Niall of the Nine Hostages. They played significant roles in the political and military affairs of Leinster.

Ulster Branch

In Ulster, particularly in County Tyrone, the Kellys were part of the Cenél Eoghain dynasty, again tracing lineage to Niall of the Nine Hostages. They were involved in regional governance and conflicts during the medieval period.

Military Involvement

The Kellys frequently engaged in battles to defend their territories against invaders, including Vikings and later the Normans and English forces. They participated in significant historical events:

• Battle of Clontarf (1014): Members of the Kelly clan fought alongside High King Brian Boru against Viking invaders.

• Conflicts with the Normans: Throughout the 12th and 13th centuries, the O’Kellys resisted Norman encroachment, striving to maintain Irish sovereignty.

Cultural Contributions

The Kelly family were patrons of Gaelic poets, scholars, and artists. Their support was crucial in preserving Irish traditions, language, and literature during times of foreign influence and suppression. The Kellys have been celebrated in Irish folklore, music, and literature. Their legacy is emblematic of Irish resilience and cultural pride.

• The Book of Ui Maine: Commissioned by William O’Kelly in the 14th century, this manuscript is a valuable source of Gaelic genealogy, poetry, and history.
