McKenna (name)

McKenna, also MacKenna and Mackenna, is the anglicized form of the Gaelic Irish surname "Mac Cionaoith", also spelt Mac Cionaodha or Mac Cionnaith, meaning "son of Cionnaith" or of the Scottish surname, from Galloway, "MacCionaodha".

The historical lineage of the McKennas lies in Truagh, County Monaghan, Ulster, Ireland, where they were "The Lords Of Truagh" and the McKenna coat of arms can be seen on many of the graves from members of the family.
