McLean

McLean is a Scottish surname, an Anglicized form of the Gaelic MacGillEathain or MacGillEain, meaning “son of the servant of Eòin.” Eòin is the Scottish Gaelic form of John, which itself derives from the Hebrew name Yoḥanan, meaning “Yahweh is gracious.” Thus, the name McLean ultimately refers to a devotee of Saint John the Baptist.

Etymology and Origins

The surname McLean comes from the Gaelic Mac Gille Eathain, a patronymic meaning “son of Gillean.” Gillean itself means “servant of (Saint) John,” referring to John the Baptist. According to clan tradition, the name is linked to Gilleathain na Tuaidh, known as “Gillian of the Battleaxe,” a legendary 5th-century warrior. The clan McLean historically held lands across the Hebrides and Highlands of Scotland, including the Isle of Mull, where their seat, Duart Castle, is located.

Historical Significance

The McLean clan rose to prominence through strategic alliances. In the 9th century, they allied with the Catholic Church, and later with powerful clans such as the MacDonalds (13th century), and the MacKays and MacLeods (16th century). The name spread throughout the Scottish diaspora, especially to North America, during the Highland Clearances and subsequent migrations.

Notable individuals with the McLean surname include American author Norman MacLean, known for his 1976 novella A River Runs Through It; Canadian singer-songwriter Don McLean, famous for the 1971 hit “American Pie”; and American astronaut Rusty Schweickart, born Russell L. Schweickart, whose surname is a variant of McLean. The surname also appears in various spellings, such as MacLean, McClean, and McLain.
