The short story
McClain is an American spelling variant of the Scottish Gaelic McLean or MacLean. The Gaelic form Mac Gill-Eain is commonly analyzed as “son of the servant of John,” with Mac marking descent and Gill-Eain preserving a devotional personal-name formation. McLean, MacLean, and MacLaine are related spelling comparisons, not a guarantee that all bearers share one branch. The surname’s direct structure is patronymic even though the older Gaelic elements have their own history.
