St. Cinnia was a 5th-century Irish princess and saint. As the sole daughter of King Echu of Ulster, she is recognized for her conversion to Christianity through the influence of Saint Patrick. To avoid a marriage arranged by her father to a man named Corburac, she sought a religious life. Following an agreement mediated by Patrick, she joined the Monastery of Druimduchan, a community of virgins led by the abbess Cathuberis, where she remained for the rest of her life.
