National Mac Day – April 12, 2025

National Mac Day is celebrated on April 12 annually. “Mac” is a common name in Scotland, Ireland, and other countries with a significant population of Irish and Scottish descendants. Most names beginning with Mac are its Christian or anglicized versions, like MacDicken, MacRitchie, and MacGuinness. The submergence of Gaelic, a Celtic language, in eighteenth-century Ireland, pushed this name into oblivion, but it still goes strong in Scotland and, to a lesser extent, Wales. Mac and Mc are often interchangeable; the latter is the short version of the former.

History of National Mac Day

The word ‘Mac means ‘son’ in the Gaelic language. In the context of surnames, this word translates as ‘son of’ and was used as a prefix to indicate the family or ancestry. The name is prominent in Scotland and Ireland. The adoption of hereditary surnames was introduced around the eleventh century when the interactions between Gaelic and Norse people influenced the naming system. The Vikings, who settled in Ireland and Scotland, intermarried with the locals, forming Norse-Gael communities that dominated the Irish and Scottish seas.

Some of the best-known Mac surnames carry traces of their Norse origin. The Irish MacManus and MacLoughlin, and the Scottish MacLachlan are some examples. The Normans, who settled in the northern part of the Frankish kingdom (modern-day France), also combined some of their names with the prefix, Mac.

By the 1800s, the use of this prefix tapered off in Ireland but remained in use by the Scottish settlers in the province of Ulster. In the seventeenth century, during the Plantation of Ulster, people from Southern Scotland and Northern England arrived to colonize Irish lands. The settlers had a different culture, with the Scots colonizers having far stronger ties to their Gaelic roots compared to the Irish there. Today, names like MacGregor, MacLeod, and MacAllan still hold relevance in parts of Scotland and Ireland, with many involved in national societies, the production of liquor, and even parliamentary proceedings.
