Origin

Meaning and origin of Condon

The surname Condon originates from Ireland, where it first appeared in the 12th century. It is an anglicized form of the Irish Gaelic name Ó Condún, meaning "descendant of Condún." Condún was a personal name derived from the Irish word "conn," meaning wise or prudent.

The name is believed to have originated in County Cork, where many early records of the Condon family can be found. The surname is particularly associated with the baronies of Condons and Clangibbon in east County Cork.

One of the earliest recorded references to the name is in the Pipe Rolls of Cloyne, a medieval document from the late 12th century, which mentions a "William de Condun." The Condon family is also mentioned in the Annals of Inisfallen, a chronicle of medieval Irish history, in the year 1295.

In the 14th century, the Condons were among the most powerful families in the region, holding significant landholdings and positions of authority. The Book of Munster, a 16th-century manuscript, records the Condon family as Lords of Condons and Clangibbon.

Notable individuals with the surname Condon throughout history include:

3. Brendan Condon (1917-2003), an Irish politician who served as a member of Dáil Éireann, the lower house of the Irish parliament, from 1954 to 1969.

4. Richard Condon (1915-1996), an American novelist best known for his satirical and political thrillers, including the novels "The Manchurian Candidate" and "Prizzi's Honor."

5. John Condon (1785-1828), an Irish-born Catholic priest and theologian who served as the first Bishop of Philadelphia in the United States.

Demographics

Ancestry and ethnicity for Condon

Among Census respondents with the surname Condon, the largest self-reported group is White at 90.8%. The next largest groups are Hispanic (3.1%) and Two or More Races (3.0%).

The bar chart below shows how Condon 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 Condon surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

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.

Why don't the ancestry percentages always add up to exactly 100%?

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.
