Surname O'Nielle - Meaning and Origin

all surnames with 'O'

O'Nielle: What does the surname O'Nielle mean?

The origin of the surname O'Nielle is Irish. It is derived from the Gaelic patronymic name "Ó Niall". The "Ó" prefixmeans "descendant of", and Niall is the Irish version of the personal name Neil meaning “champion”.

The O'Neil family of Ireland were a powerful and influential clan present in many regions of the island, with branches in both Ulster and Munster. The family is descended from Niall of the Nine Hostages, who was a fifth-century High King of Ireland. He is thought to have established the kingdom of Ailech, located in what is now Tyrone.

With time, the O'Neal name has adopted various forms including McNeil, Neill, Neil and Niall. Famous variants of the O'Neil surname include former president of Ireland, Mary McAleese; Irish politician John McNeil; Canadian journalist and author Cathy O'Neil; American-Colombian singer songwriter, Kali Uchis; and legendary American baseball player Phil Niekro.

The Gaelic words “Niall” and “Ó”, and the anglicised version Newman and Niel, all refer to this one great Irish surname. The O'Neil clan had a long and turbulent history due to old rivalries and constant clan warfare, but the name still survives today as a testament to their strength and resilience. O'Neil remains to be a symbol of clan unity in certain regions around Irish, and it is just as popular on the other side of the world.

When the O'Nielle family first arrived in the United States in the late 1800s, they settled mostly in large metropolitan areas such as Boston, New York, and Chicago. Later generations spread out into other parts of the country. Today, the greatest number of O'Nielles reside in the northeastern US, with significant numbers in Massachusetts, New York, Pennsylvania, and New Jersey.

Several smaller populations of O'Nielles appear in other areas, such as Oregon, Florida, Texas, and Michigan. During the 20th century, many members of the O'Nielle family left the US for other countries such as Canada, Australia, and the United Kingdom. As a result, the last name O'Nielle is also found in these countries today.

Overall, the last name O'Nielle is not as common today as it was in the early 20th century. It has become increasingly rare in the United States over the past few decades, although its historic ties to the northeastern US remain strong and members of this family can still be found in numerous parts of the country.
