McCaig

McCaig is a Scottish surname. It is generally considered a variant of the Gaelic surname MacCaig, meaning "son of Caig." The given name "Caig" is thought to be derived from a diminutive of names such as Isaac. The surname is most prevalent in western Scotland, particularly in the Argyll region.

The name McCaig is also associated with a notable folly located in Oban, Argyll and Bute, Scotland, known as McCaig's Tower. Built in the late 19th century by John Stuart McCaig, a banker and philanthropist, the tower resembles a Roman colosseum and was intended to provide employment for local stonemasons and serve as a family mausoleum and art gallery.

Variants of the surname include MacCaig, McCage, McKeague, and others, reflecting the historical variations in spelling and pronunciation common in Gaelic and Scottish surnames. Individuals with the McCaig surname can be found throughout the world, largely as a result of emigration from Scotland.
