History & Origin

Cionna has no firmly recorded etymology. Its nearest documented neighbour is Sionna, the Irish name of the goddess associated with the River Shannon, and it also sits close to Ciara ('dark-haired') and Fiona. Because a sound-alike is an echo rather than descent, we present Cionna honestly as a modern spelling of uncertain route (said 'see-OH-nuh').

It appears only in very small numbers in the U.S. Rare, flowing, and modern.

Did you know? Sionna is the Irish name behind the River Shannon and the goddess said to have given it her name - Cionna echoes it without a documented line back.
