McKay

If there's one thing you'll be doing when baby arrives into your life, it's going to be celebrating. McKay, sometimes stylized as Mckay, is a gender-neutral name with Scottish roots that means "happy" or "rejoicing." It also has origins as an Irish surname. Meaning "son of Aodh," it comes from the Irish mac Aodha. With Aodh being the root of names like Aidan and Hugh, McKay can be an understated way to honor family names. It's also a more unusual alternative to Mckayla.
