Origin
Meaning and origin of Mcglaughn
The surname McGlaughn originated in Scotland in the 12th century. It is thought to be derived from the Gaelic words "mac" meaning "son of" and "Gille Fhalachain" meaning "servant of the enclosure". The name likely referred to someone who worked within an enclosed area or churchyard.
One of the earliest recorded examples of this name is John McGlaughn, who was born around 1275 in Ayrshire, Scotland. Records show he was a landowner in the parish of Galston. Another early bearer was William McGlaughn, born around 1320 in Lanarkshire, who served as a soldier in the Scottish army during the Wars of Scottish Independence against England.
In the 16th century, the McGlaughn name appears in the Court Books of Orkney and Shetland, suggesting bearers had migrated to these northern islands. One such example is Magnus McGlaughn, born around 1550 in Westray, Orkney, who worked as a fisherman and crofter.
The McGlaughn surname is also found in early records from Ireland, likely originating from Scottish settlers. Patrick McGlaughn, born around 1610 in County Antrim, was a farmer and landowner mentioned in the Hearth Money Rolls of the 1660s. Another bearer was Seamus McGlaughn, born around 1685 in County Down, who fought in the Williamite War in Ireland in the late 17th century.
Notable people with this surname include Robert McGlaughn (1688-1766), a Scottish merchant and politician who served as Lord Provost of Edinburgh in the mid-18th century. In the United States, Thomas McGlaughn (1810-1892) was an early settler in Ohio and operated a successful farm and mill. Elizabeth McGlaughn (1864-1953) was a Scottish educator who campaigned for women's rights and improving access to education.

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 Mcglaughn surname at the time of the 2020 Census, not any inherent property of the name itself.
