MacThaoig

MacThaoig is a Scottish Gaelic surname, the original form of the anglicized name McCaig. The name is a patronymic, meaning "son of Tadhg"—Tadhg itself being a Gaelic name of ancient origin.

Etymology and Linguistic Origin

The root of MacThaoig lies in the Old Irish name Tadg, which means "poet" or "storyteller." This connection underscores the traditional Gaelic value placed on oral poetry and wisdom. The name Tadhg has been borne by numerous Irish kings and chieftains, including an 11th-century king of Connacht, and appears in Irish mythology as the name of the grandfather of Fionn mac Cumhaill.

Anglicization and Distribution

As with many Gaelic surnames, MacThaoig underwent anglicization during the process of English-language administration and cultural change in Scotland and Ireland. The variant McCaig emerged through phonetic approximation and spelling standardization. Today, MacThaoig is less common than its anglicized relative, but it persists in areas with strong Gaelic heritage, particularly in the Scottish Highlands and islands. The name also has Irish cognates such as Mac Thaidhg and Ó Taidhg, as well as anglicized forms like Teague and Tighe.
