MacEalair is a Scottish surname, the Gaelic form of McKellar. Both surnames trace back to the Gaelic MacEalair, meaning "son of Ealar," where Ealar is the Scottish Gaelic form of the Latin-derived name Hilary.
Etymology
The name Hilary ultimately derives from the Latin Hilarius (masculine) or Hilaria (feminine), meaning "cheerful" or "joyful." In medieval Scotland, the Gaelic form Ealar emerged, and the patronymic MacEalair signified "descendant of Ealar." Through Anglicization, MacEalair became McKellar, a more widespread surname today.
Cultural Context
MacEalair is a rare surname, reflecting the strong Scottish Gaelic naming tradition of clan affiliation through patronymics. The variant McKellar is more common, notably associated with the McKellar family of the Scottish Highlands. The availability of the name in historical records is limited, but its Gaelic origin ties it to the linguistic heritage of Scotland, where many surnames beginning with Mac denote "son of."
