McIntosh
A Scottish Gaelic surname meaning “son of the chief” or “son of the leader.”
The #819 most common surname in the United States (2010 Census) — about 1 in every 7,285 Americans shares it.
Etymology
McIntosh comes from Scottish Gaelic Mac an Toisich, literally “son of the toiseach.” The Gaelic word toisich/toiseach refers to a leader, first man, or chief, so the name was originally a patronymic tied to rank or office rather than to a personal given name. In older anglicized spellings, it can appear as Mackintosh or MacKintosh.
History
The name is long associated with the Highland clan Macintosh, one of the better-known Gaelic families of Scotland. Historical surname writers often gloss it as “son of the chief” or “son of the prince,” reflecting the prestige sense of the Gaelic root. The spelling McIntosh became common in English usage alongside Mackintosh and other reduced forms.
