Died c. 650. Saint Osmanna was descended from an illustrious Irish
family. She migrated to Brittany in northern France to live as a
consecrated virgin and served God with fervour in solitude until her
death near Saint Brieuc. Until the Reformation, her relics were
enshrined in a chapel under her patronage in the abbatial church of
Saint Denys near Paris; but some of them
were dispersed by the Calvinists in 1567
