Origin
The surname Derry is believed to have originated in Ireland and is derived from the Irish Gaelic word "doire," which means "oak grove" or "oak wood." The name is closely associated with the city of Derry, also known as Londonderry, in Northern Ireland.
The earliest recorded instances of the name Derry can be found in ancient Irish manuscripts and records dating back to the 12th century. It is believed that the name was initially used as a descriptive term for individuals who lived near or worked in oak groves or forests.
One notable historical reference to the name Derry is found in the Annals of Ulster, a chronicle of medieval Irish history. The Annals mention several individuals with the surname Derry, suggesting that the name was well-established in Ireland by the 13th century.
In the 16th century, during the Plantation of Ulster, many English and Scottish settlers arrived in the region, and the name Derry became more widespread. The city of Derry itself was an important center of trade and commerce during this period, and it is likely that the surname gained prominence as a result.
One of the earliest recorded individuals with the surname Derry was John Derry, who was born in County Tyrone, Ireland, around 1550. He was a prominent landowner and local official during the Plantation of Ulster.
Another notable figure was Sir Edward Derry (1598-1667), an English soldier and politician who served as Governor of the Isle of Man and played a significant role in the English Civil War.
In the 18th century, the surname Derry was found in various parts of Ireland, as well as in areas of Scotland and England where Irish immigrants had settled. One notable individual from this period was William Derry (1720-1789), an Irish-born artist and engraver who worked in London and is known for his portraits and landscapes.
In the 19th century, the Derry surname spread further as Irish immigration to the United States and other parts of the world increased. One prominent individual from this era was Reverend James Derry (1822-1902), an Irish-born Presbyterian minister who served in several churches in the United States and was a vocal advocate for temperance and abolition.
Another notable figure was Joseph Derry (1861-1938), a Canadian-born businessman and politician who served as a Member of Parliament in the Canadian House of Commons and was involved in various mining and industrial ventures.
Throughout history, the surname Derry has been associated with individuals from diverse backgrounds and professions, reflecting its Irish origins and the dispersal of Irish people around the world.
Demographics
Among Census respondents with the surname Derry, the largest self-reported group is White at 76.9%. The next largest groups are Black (12.6%) and Two or More Races (5.1%).
The bar chart below shows how Derry 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 Derry 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.
