Origin
The surname Kearney is of Irish origin, derived from the Gaelic surname Ó Catharnaigh, which means 'descendant of Catharnach'. Catharnach was a personal name derived from the Irish word 'catharnach', meaning 'warrior' or 'battler'.
The Kearney name has its roots in County Sligo, Ireland, where the family was part of the ancient Uí Fiachrach dynasty that ruled the region. The Kearneys were one of the principal families of Sligo and held significant territories in the area.
The name is first recorded in the Annals of the Four Masters, a chronicle of medieval Irish history, in the 12th century. The Annals mention several notable members of the Kearney family, including Donnchadh Ó Catharnaigh, who was described as the Lord of Triath-na-Sionainne (Tírenashingane) in County Sligo in 1180.
The Kearney name appears in various historical records throughout the centuries. One of the earliest recorded instances is in the Pipe Roll of Cloyne, a 13th-century document listing landowners in County Cork, which mentions a William de Kerdeny.
Another notable figure with the Kearney name was Patrick Kearney (1597-1661), an Irish Catholic priest and scholar who served as the Archbishop of Cashel from 1629 to 1661. He played a significant role in the Irish Confederate Wars and was a supporter of the Catholic Confederacy.
In the 17th century, the Kearney family was among the Catholic landowners who lost their estates during the Cromwellian conquest of Ireland and the subsequent Plantation of Ulster. Many Kearneys were forced to relocate to other parts of Ireland or emigrate to continental Europe.
John Kearney (1742-1786) was an Irish-born soldier who served in the American Revolutionary War. He fought for the Continental Army and was appointed as a Lieutenant Colonel in the 9th Pennsylvania Regiment.
Sarah Kearney (1805-1858) was an Irish poet and author, best known for her work "The Bard's Legacy", which was published in 1831. She was born in County Roscommon and her poetry often explored themes of Irish culture and identity.
Demographics
Among Census respondents with the surname Kearney, the largest self-reported group is White at 73.3%. The next largest groups are Black (18.8%) and Two or More Races (3.7%).
The bar chart below shows how Kearney bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Kearney surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
