Surname Ó hUallacháin - Meaning and Origin

all surnames with 'O'

Ó hUallacháin: What does the surname Ó hUallacháin mean?

The surname Ó hUallacháin is an ancient Gaelic Irish name, derived from the Irish words ‘Ó’, meaning ‘grandson’, and ‘Uallachán’, meaning ‘valiant’. This surname is found mainly in County Cork and Munster in Ireland.

The root of the surname, ‘Uallach’, was an Irish given name and derived from the Old Irish ‘uallach’, meaning ‘valiant’. The Irish ‘uallach’ ultimately comes from the Latin ‘valens’. This surname was also connected to the sept of the Cianacht of Cashel, and traditionally they were a branch of the O’Keeffes and the rulers of the territory of Muskerry.

The genealogical internet site Irish Origenes states that, ‘The O'HUallachain sept were from the district of Muskerry, now the barony of Muskerry, County Cork, and were a branch of the O'Keeffe sept who were chiefs of the territory of Muskerry’.

In more recent history, the name Ó hUallacháin was recorded in a list of nineteenth century Irish emigrants to the United States. Indeed, the name has been carried with Irish immigrants to many parts of the world, including the UK and Canada.

In modern Irish, the surname is written Ua hUallacháin, though it is now usually anglicized as Walsh or Wallace.
