Origin

Meaning and origin of Cochran

The surname Cochran is of Scottish origin, derived from the Gaelic personal name "Ochógan," meaning "descendant of the young one." The name is believed to have originated in the region of Ayrshire in southwestern Scotland during the early Middle Ages.

The earliest recorded instances of the name can be traced back to the 13th century, with references in several Scottish charters and records. One of the earliest known bearers of the name was William de Coughran, mentioned in the Ragman Rolls of 1296, a collection of homage renderings to King Edward I of England.

The surname Cochran is also linked to several place names in Scotland, such as Cochrane in Renfrewshire and Cochran in Dumfriesshire. These place names likely derived from the surname itself, reflecting the connections between families and the lands they owned or occupied.

Throughout history, several notable individuals have borne the surname Cochran. One of the most prominent was Robert Cochran (c. 1440-1482), a Scottish courtier and favorite of King James III, who was eventually executed for treason. Another notable figure was Robert Cochran (1758-1826), a Scottish-American soldier and politician who served as a brigadier general during the American Revolutionary War.

In the realm of literature, the surname is associated with the Scottish author William Cochrane (1605-1685), best known for his theological works. The name has also graced the pages of history through individuals like Sir Ralph Cochrane (1609-1680), a Scottish soldier and landowner, and Thomas Cochrane, 10th Earl of Dundonald (1775-1860), a renowned British naval officer and radical politician.

Other notable bearers of the surname Cochran include Robert Cochran (1914-2006), an American film and television writer and producer known for his work on iconic shows like "The Fugitive" and "Columbo," and John Cochran (1813-1898), a Scottish-American chemist and geologist who served as the president of the Franklin Institute in Philadelphia.

Demographics

Ancestry and ethnicity for Cochran

The bar chart below shows how Cochran 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 Cochran 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 Cochran (2000, 2010, 2020).

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.
