O’Hara – ancient Irish clan of Sligo

O’Hara is a popular name around the world. It originated in ancient Ireland at some time before the 10th century. During the 1800s, the name was spread around the world, to America, Britain and Australia as millions of people were forced to leave Ireland because of the ‘Great Famine’.

It is now a fairly common name in most English speaking countries.

One of these clans was the O’hEaghras. They held territory in County Sligo. The O’hEaghras were descendants of a man named Eaghra, who was a member of the powerful household of Ollum, King of Munster.

Eaghra gained his own territory in Sligo, and when he passed the leadership of the family down to his son, the family name became O’hEaghra. The ‘O’ prefix in Ireland refers to the ‘grandson of’ or ‘descendant of’.

The family owned large areas of land in Sligo and remained a powerful force up until the 16th century. Then Oliver Cromwell’s invasion of Ireland saw the O’hEaghra’s land confiscated and handed over to British settlers. Like most clans in Ireland, the O’hEaghras couldn’t defend themselves against the military power of Cromwell. Their land was taken and they had to re-integrate themselves into the changing Irish-British society.

At this time, many of the traditional Irish names evolved into more English sounding versions, and O’hEaghra became O’Hara.Maureen O'Hara It became a popular name around the world when thousands left Ireland during the ‘Great Famine’ of the mid-19th century.
