Origin

Meaning and history of Oconner

The name Oconner is of Irish origin, derived from the Gaelic personal name "Ó Conchobhair," meaning "descendant of Conchobhar." Conchobhar is an ancient Irish name composed of the elements "con" meaning hound, and "cobhar" meaning help or aid. The name can be traced back to the 7th century AD, and it was one of the most prominent surnames in medieval Ireland.

In Irish mythology, Conchobhar mac Nessa was a legendary king of Ulster who played a central role in the epic tales of the Ulster Cycle. He was known for his wisdom, courage, and his tragic love for the beautiful Deirdre of the Sorrows. The name Oconner was borne by many Irish kings, chieftains, and warriors throughout history.

One of the earliest recorded examples of the name Oconner is Domhnall Ua Conchobhair, who was the King of Connacht and High King of Ireland from 1156 to 1186. He was a powerful ruler who fought against the Anglo-Norman invasion of Ireland and defended his kingdom against the English crown.

Another notable figure was Turlough O'Conor, who was the King of Connacht from 1106 to 1156. He was a skilled military leader and diplomat, known for his alliances with the Norman invaders and his efforts to maintain peace and stability in Ireland.

In the 16th century, Hugh O'Conor Don was an Irish chieftain and the last inaugurated Prince of Sligo. He led the resistance against the English conquest of Ireland and was eventually captured and executed in 1642.

Roderic O'Conor, also known as Rory O'Conor, was the last High King of Ireland before the Norman invasion. He ruled from 1166 to 1198 and is remembered for his attempts to unite the Irish clans against the English invaders.

Charles O'Conor, born in 1710, was an Irish historian and antiquarian who made significant contributions to the study of Irish language and literature. He published several important works, including "Rerum Hibernicarum Scriptores Veteres" and "Ogygia, seu Rerum Hibernicarum Chronologia."

These are just a few examples of the many notable individuals who have borne the name Oconner throughout history, reflecting its deep roots in Irish culture and its association with leadership, valor, and scholarship.

FAQ

Oconner: questions and answers

How many people in the U.S. are named Oconner?

Name Census puts the figure at roughly 5 living Americans. We arrive at this by taking every SSA birth registration for Oconner going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 68,550,868 US residents.

Is Oconner a common name?

We classify Oconner as "Very Rare". It ranks above 18.2% of all first names in the SSA dataset by living bearers. Across the full history of the data, 5 babies have been registered with this name.

When was Oconner most popular?

The single biggest year for Oconner was 2018, when 5 babies received the name. The fact that the average living Oconner is about 8 years old gives you a rough sense of which era contributed the most bearers who are still alive today.

What does the SSA popularity chart show?

The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Oconner in that year. That makes it useful for spotting when the name rose, peaked, or faded.

Is Oconner a male name?

Yes, 100.0% of people registered as Oconner in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.

Is Oconner still being used today?

Yes. The SSA still recorded Oconner in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.

Why can a name have a lot of living bearers even if it is not trendy now?

Because living-bearer counts and current baby-name popularity measure different things. A name like Oconner can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.

Where does this data come from?

First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.

Does every first name have Census demographic data?

No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
