McDougall is a Scottish surname, a variant of MacDougall. Like its parent form, McDougall means "son of Dougal," deriving from the Gaelic patronymic Mac Dubhghaill.EtymologyThe surname traces its roots to the Gaelic personal name Dubhghall, which is composed of Old Irish dub "dark" and gall "stranger." The original sense of "dark stranger" likely referred to the Norse Vikings, as opposed to the "fair strangers" (the Danes). The name was borne by several medieval Scottish chiefs, notably the MacDougall Lords of Argyll. The spelling McDougall reflects the anglicized form, with the prefix Mc- being a contraction of Mac ("son of"). Alternative spellings include MacDougall, McDowell, and Dougal, while the Gaelic original is Dubhghall.Historical BearersThe MacDougall clan historically held lands in Argyll and the Isles, descending from Somerled, 12th-century King of the Hebrides. The clan's name is also anglicized as MacDowall in some branches. A notable modern bearer is William McDougall (1822–1905), a Canadian politician whose name was commemorated in McDougall, Ontario, a township named after him.Related NamesVariants and cognate surnames exist across the Goidelic languages. In Irish, the name is Anglicized as Doyle or O'Doyle (from Ó Dubhghaill). The variant McDowell is especially common in Scotland and Ulster.Meaning: Son of the dark strangerOrigin: Scottish Gaelic (Mac Dubhghaill)Type: Patronymic surnamePrimary Regions: Scotland, Canada, United States, Australia
