Mionna is of Scottish origin, derived from the Gaelic word 'Mionnach', which means 'peaceful'. It is a unique and beautiful name that has gained popularity in recent years. Mionna was traditionally given to girls born on a Monday, reflecting the old Celtic belief that each day of the week had its own patron saint or goddess.
"Mionna is a relatively uncommon name, with an average of about six babies being named Mionna each year over the past two decades."
