Mckenna — Lords of Truagh

McKenna comes from Mac Cionaoith, built on the personal name Cionaodh — a name also carried by early Scottish kings. The family ruled Truagh, a territory straddling the modern Monaghan-Tyrone border, as one of the lesser lordships of Airgíalla.

A name shared, by coincidence of an old personal name, with the royal line of Scotland — though the McKennas built their own, smaller kingdom on their own ground.
