Mckenna

An Anglicized form of the Gaelic surname Mac Cionaodha, originally denoting descent from a personal name associated with fire. It spent centuries functioning solely as a family name in Ireland and Scotland. American parents adopted it as a feminine given name in the final decades of the twentieth century, riding the broader wave of surname transfers.

The name reads as modern, sociable, and thoroughly post-1990. It suggests someone who grew up with an organized soccer schedule and a color-coded binder. With an average age around eighteen, the name carries no mid-century baggage whatsoever. Automated databases still occasionally choke on the interior capital letter.
