Kaius

Boy name · 3 babies recorded · 1974–2025

Kaius: 3 babies born in Scotland since 1974, given to boys, peaking at 3 births in 2023.

Kaius is a Latin name, derived from the ancient Roman name Caius, which is thought to mean "rejoice" or perhaps originates from an Etruscan root. It was borne by Pope Caius, a third-century saint, and later by John Caius, the English physician who co-founded Gonville and Caius College, Cambridge—a place forever tied to the name. In modern Scotland, Kaius is a distinctive variant of the more familiar Kai, offering a classical twist that parents might find both strong and uncommon.
