Origin
Meaning and origin of Mcclarney
The surname McCLARNEY is of Irish origin, originating from the Gaelic Mac Fhloirchinnéidh, which means "son of Floirchinnéidh."

The McCLARNEY surname is most commonly found in County Donegal, Ireland, particularly in the Barony of Boylagh and the Barony of Raphoe. The earliest recorded instances of the name date back to the 16th century in this region.
One of the earliest recorded McCLARNEYs was Fergus McCLARNEY, who was listed in the Hearth Money Rolls for County Donegal in 1663. These rolls were a form of census and tax collection in Ireland during this time period.
In the 18th century, there are records of a McCLARNEY family residing in the townland of Gortnavarnoge, near Letterkenny, County Donegal. The head of this family was Patrick McCLARNEY, who was born around 1720.
Another notable McCLARNEY was Randal McCLARNEY, a Catholic priest who lived in the late 18th and early 19th centuries. He served as the Parish Priest of Killaghtee, County Donegal, from 1790 until his death in 1828.
In the 19th century, the name McCLARNEY was also found in the nearby counties of Tyrone and Derry. One example is James McCLARNEY, a farmer from County Tyrone who was born around 1820.

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

Is this page using the latest Census data?

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.
