Origin
The surname Gibney is of Irish origin and can be traced back to the 11th century. It is derived from the Gaelic personal name "Gibbon," which means "little hawk" or "falcon." The name was initially found in County Monaghan, Ireland, where it was prominent among families living in the baronies of Farney and Cremorne.
One of the earliest recorded instances of the Gibney name appears in the Annals of Ulster, a chronicle of medieval Irish history. In 1134, a chieftain named Gilla-na-noev O'Gibney is mentioned as a leader of the Ui Meith, a powerful dynasty in County Monaghan.
During the 16th and 17th centuries, the Gibney family played a significant role in the Irish Confederate Wars, supporting the Catholic cause against English forces. In 1641, Edmond Gibney, a landowner from County Monaghan, joined the Irish Rebellion and fought alongside Owen Roe O'Neill's troops.
The Gibneys were also known for their involvement in the literary and ecclesiastical spheres. In the 18th century, Father Patrick Gibney (1720-1789) was a renowned Irish scholar and author who wrote extensively on Irish history and culture.
Another notable figure was John Gibney (1825-1903), a prominent Irish lawyer and politician. He served as a Member of Parliament for the constituency of Meath from 1880 to 1885 and played a crucial role in the Irish Home Rule movement.
In the 20th century, James Gibney (1915-1997) gained recognition as a respected American novelist and short story writer. His works often explored themes of Irish-American identity and the immigrant experience.
Other individuals with the Gibney surname who have made significant contributions include:
1. Norah Gibney (1892-1956), an Irish poet and playwright known for her works on Irish mythology and folklore.
2. Frank Gibney (1924-2006), an American journalist and author who covered Asia and wrote extensively about Japan and China.
3. Erin Gibney (born 1975), an American artist and sculptor whose works have been exhibited in various galleries and museums across the United States.
4. John Gibney (born 1949), an Irish politician and former member of the European Parliament, representing the Dublin constituency.
5. Michael Gibney (born 1967), an Irish chef and food writer who has authored several cookbooks and served as a judge on the television show "MasterChef Ireland."
Demographics
Among Census respondents with the surname Gibney, the largest self-reported group is White at 92.2%. The next largest groups are Hispanic (3.3%) and Two or More Races (2.9%).
The bar chart below shows how Gibney 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 Gibney surname at the time of the 2020 Census, not any inherent property of the name itself.

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Gibney (2000, 2010, 2020).
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.
