Origin
The surname OLNEY is of English origin, tracing its roots back to the medieval period. It is a locational name derived from the town of Olney in Buckinghamshire, England. The name Olney itself is believed to come from the Old English words "ole" meaning "a source or spring" and "eg" meaning "an island or low-lying land surrounded by water or marshy ground."
One of the earliest recorded mentions of the name OLNEY can be found in the famous Domesday Book of 1086, where it appears as "Ollenei." This suggests that the name was already well-established in the region by the late 11th century.
In the 13th century, a notable figure named John de Olney was mentioned in the Pipe Rolls of Gloucestershire in 1230. This indicates that the surname had begun to spread beyond its original geographical roots.
During the 16th century, the name OLNEY gained prominence with the birth of John Olney (c. 1515-1564), an English clergyman and Protestant martyr who was burned at the stake for his religious beliefs during the Marian persecutions.
Another notable bearer of the OLNEY surname was Thomas Olney (c. 1600-1654), one of the founders of Providence, Rhode Island, and a close associate of Roger Williams. He was among the first settlers of the colony and played a significant role in its early development.
In the 18th century, Baptismal records from the town of Olney in Buckinghamshire show the name OLNEY being used consistently among local families, cementing its longstanding connection to the area.
William Olney (1786-1859), an English mathematician and educator, was a prominent figure in the 19th century. He authored numerous mathematical textbooks and served as the headmaster of the prestigious Prospect House School in Twickenham.
Throughout history, the OLNEY surname has also been associated with notable figures in various fields, including literature, politics, and science, further contributing to its rich heritage.
Demographics
Among Census respondents with the surname Olney, the largest self-reported group is White at 85.5%. The next largest groups are Two or More Races (4.4%) and American Indian/Alaska Native (4.1%).
The bar chart below shows how Olney 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 Olney 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.
