Origin
The surname Galigher has its origins in Ireland, with the earliest known references dating back to the 16th century. It is believed to have derived from the Gaelic word "gaillbhear," which translates to "foreign tiller" or "stranger farmer." This suggests that the name may have been given to an immigrant farmer who settled in Ireland from another region.
In the Annals of the Four Masters, a chronicle of medieval Irish history, there is a mention of a "Donell Boy Galigher" in the year 1586. This is one of the earliest recorded instances of the name being used. Additionally, the surname appears in the Fiants of the Reign of Elizabeth I, a collection of official documents from the late 16th century.
The Galigher name can also be found in various land and parish records from the 17th and 18th centuries, primarily in counties such as Donegal, Tyrone, and Fermanagh. Some of the earliest known bearers of the name include John Galigher, who was born in County Donegal around 1650, and Patrick Galigher, who was born in County Fermanagh in the late 17th century.
One notable individual with the Galigher surname was Robert Galigher, a prominent 18th-century merchant and landowner from County Tyrone. He was born in 1725 and played a significant role in the economic development of the region. Another notable figure was James Galigher, a soldier who fought in the Battle of Waterloo in 1815 and later settled in County Donegal.
Throughout the 19th century, the Galigher name continued to be found in various records and documents across Ireland. One notable bearer was Michael Galigher, a writer and poet who was born in County Fermanagh in 1848. He wrote extensively about Irish culture and history.
In the mid-19th century, many individuals with the Galigher surname immigrated to other parts of the world, particularly to North America and Australia, due to the Great Famine and other economic and political factors. One such individual was John Galigher, who was born in County Donegal in 1820 and later settled in Ontario, Canada, where he became a successful farmer and community leader.
The Galigher surname has also been associated with various place names and locations in Ireland, such as Galigher's Brae, a townland in County Fermanagh, and Galigher's Cross, a crossroads near the village of Ballinamallard in County Fermanagh.
Demographics
Among Census respondents with the surname Galigher, the largest self-reported group is White at 82.9%. The next largest groups are Two or More Races (9.0%) and Black (5.4%).
The bar chart below shows how Galigher 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 Galigher 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.
