McLain

McLain is a Scottish surname, a variant of McLean. Like McLean, it is an Anglicized form of the Gaelic MacGillEathain or MacGillEain, meaning "son of the servant of Eòin." The personal name Eòin is the Scottish Gaelic form of Iohannes (see John), which ultimately derives from the Hebrew Yoḥanan, meaning "Yahweh is gracious." Thus, McLain carries the layered meaning of "son of the servant of John."

McLain is predominantly found in Scotland, particularly in the Highlands and Hebrides, where the Clan MacLean (also spelled Maclaine) held significant territories. The name boasts a rich history tied to the clan system of Scotland. Notable historic clan figures include the MacLeans of Duart and the MacLaines of Lochbuie.
