Origin
The surname Donley originated in Ireland, specifically in the northern counties of Ulster. It first appeared in written records during the 17th century. The name is derived from the Gaelic words "donn" meaning brown or dark, and "leath" meaning a portion or side. Together, the words form the meaning "brown side" or "dark slope."
This surname is believed to have originated as a topographic name, referring to a person who lived near a brown or dark-colored hillside or slope. It may have also been used as a descriptive name for someone with a dark complexion or hair color.
One of the earliest recorded instances of the name can be found in the Hearth Money Rolls of 1665, which listed a John Donley residing in County Antrim, Ireland. The name also appeared in the Registry of Deeds for County Donegal, where a William Donley was recorded as a landowner in 1672.
During the 17th and 18th centuries, many Irish families with the surname Donley immigrated to the American colonies, particularly to Pennsylvania and the Appalachian region. Notable individuals with the Donley surname include:
1. James Donley (1737-1806), an Irish-born American soldier who fought in the Revolutionary War and later settled in Virginia.
2. John Donley (1771-1856), an American farmer and landowner in Ohio, known for his contribution to the early settlement of the state.
3. Sarah Donley (1822-1905), a pioneer and one of the first female settlers in California during the Gold Rush era.
4. William Donley (1848-1924), an American businessman and politician who served as the mayor of Wheeling, West Virginia, from 1893 to 1895.
5. Margaret Donley Noonan (1867-1945), an American educator and women's rights activist who worked to establish educational opportunities for girls in rural Pennsylvania.
Throughout its history, the Donley surname has also been associated with various place names in Ireland, such as Donleys Brae in County Antrim and Donleys Hill in County Tyrone. These place names likely originated from the presence of Donley families in those areas and reflect the topographic nature of the surname.
Demographics
Among Census respondents with the surname Donley, the largest self-reported group is White at 82.5%. The next largest groups are Black (9.0%) and Two or More Races (3.9%).
The bar chart below shows how Donley 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 Donley 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.
