Origin
The surname McKinnerney has its origins in Ireland, tracing back to the 16th century. It is derived from the Gaelic "Mac Ionnraidh," meaning "son of Ionnraidh," with Ionnraidh being a personal name derived from the word "ionradh," meaning "a wanderer" or "a traveler."
The earliest recorded instances of the name can be found in historical documents from County Donegal, where it was particularly prevalent in the baronies of Kilmacrenan and Raphoe. The name is believed to have originated in this region, with its bearers being descendants of a prominent clan or sept.
One of the earliest known references to the name is found in the Annals of the Four Masters, a chronicle of medieval Irish history. The annals mention Turlough McKinnerney, who was slain in a battle in 1522. This record provides evidence of the name's existence and use during the 16th century.
In the 17th century, the surname McKinnerney appears in various legal documents and land records from County Donegal. One notable bearer of the name was Phelim McKinnerney, who was granted lands in the parish of Killybegs in 1666 as part of the Plantation of Ulster.
As the McKinnerney family spread throughout Ireland, variations in the spelling of the name emerged, including McKennerney, McKenerreny, and McKinerney. These variations were often influenced by the local dialects and pronunciation of the name in different regions.
Notable individuals with the surname McKinnerney throughout history include:
1. John McKinnerney (1768-1835), an Irish poet and songwriter from County Donegal, known for his works in the Irish language.
2. Bernard McKinnerney (1838-1911), an Irish-American politician who served as a member of the United States House of Representatives from Connecticut.
3. James McKinnerney (1860-1926), an Irish-born prelate of the Roman Catholic Church who served as the Bishop of Wilmington, Delaware.
4. William McKinnerney (1889-1967), an Irish-American labor leader and politician who served as the President of the International Brotherhood of Electrical Workers.
5. John McKinnerney (1922-2005), an Australian rules footballer who played for the Fitzroy Football Club in the Victorian Football League (now known as the Australian Football League).
While the surname McKinnerney has its roots in Ireland, it has since spread to various parts of the world due to Irish emigration, with bearers of the name found in countries such as the United States, Canada, Australia, and New Zealand.
Demographics
Among Census respondents with the surname Mckinnerney, the largest self-reported group is White at 86.9%. The next largest groups are Hispanic (9.1%) and Black (2.0%).
The bar chart below shows how Mckinnerney 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 Mckinnerney 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 Mckinnerney (2000, 2010, 2020).
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.
