Meaning and Origin – the fascinating story behind the name

O'Neill surname meaning and origin.

The fact that this last name starts with an ‘O’ is not uncommon. This is a real giveaway that the name originates in Ireland.

Back in the day, either the ‘O’ or the ‘Mac’ before the name was a way of explaining that you were a descendant of someone in particular.

The Irish last name O’Neill is an anglicised version of the Irish name Ua Neill, where ‘Ua’ meant grandson or descendent, just as ‘O’ and ‘Mac’ did. The name comes from the Irish first name Niall, meaning ‘champion’.

For the name O’Neill, the meaning is the descendant of Neill – which is a given name also of Irish origin. The origins of O’Neill go way back to the fifth-century former warrior King of Ireland by the name of Niall Noigiallach.

St Patrick.

This man was once said to have brought St Patrick to Ireland, who then became our patron saint, celebrated on 17 March every year.

The O’Neill’s originated in the province of Ulster and has its special coat of arms, which many other Irish names have too, as well as being linked with a branch of the Ui Neill dynasty.

The coat of arms has its own very interesting story behind it. As the legend would have it, the symbol of the red hand seen in the emblem came about when the land was promised to the first man who could sail or swim to the shores of Ireland.

This promise saw one man known as O’Neill chop off his left hand and throw it to the shore, ensuring he won the land – and that he did. Since the 1920s, this symbol has been used by protestant inhabitants of Northern Ireland.
