Meaning and origin

Over time, the name has spread beyond Ireland, particularly among the Irish diaspora, and has become a relatively common surname in the English-speaking world.

The longer story

The last name McKenna has Irish origins and is classified as a surname. It is believed to be an Anglicized form of the Irish name Mac Cionaoith, which translates to "son of Cionnaoith." The prefix "Mac" signifies "son of" in Gaelic, indicating that the surname was passed down through generations.

The name Cionnaoith, on the other hand, has a distinct etymology. It is derived from a combination of the Gaelic words "cion" and "aithe," meaning "respect" and "hospitality" respectively, resulting in the overall meaning of "one who is respectful and hospitable."

As with many surnames, the spelling and pronunciation of McKenna have evolved over time. Various alternate spellings, including McKenne, MacKenne, and MacKenna, can be found throughout historical records. These variations offer insight into the fluidity of name spellings and the transition from Gaelic to English languages.
