Etymology

As a Scottish and Irish surname, it is Anglicised from Mac Cionaodha or Mac Cionaoith. As an Irish surname it is also Anglicised from Mac Coinnigh, meaning “son of Coinneach”, which in Scotland is also treated as equivalent to Kenneth. Both senses come from Pictish *ᚉᚔᚅᚔᚑᚇ, and in Scotland the name is sometimes Anglicised as McKenzie.
