History & Origin

Koni is a modern K-spelling of Connie, the pet form of Constance, from Latin constantia, 'steadfastness'. Trading C for K was a small, fashionable way to freshen a familiar nickname in the middle of the century.

It stayed genuinely rare, only a handful of girls a year at its high around 1964, and faded within a generation. It keeps company with Connie, Coni and Constance.

Did you know? Koni just swaps the C of Connie for a K — the same cosmetic switch that gave the era Kathy for Cathy and Karol for Carol.
