St. Dymphna

St. Dymphna was just 15 when she was martyred in defense of her purity. After the death of her mother, Dymphna's father became afflicted with a mental illness and attempted to marry his own daughter. Dymphna fled along with St. Gerebran and her confessor. However, her father found her and when she refused to go back with him, he cut off her head. St. Dymphna is patroness of those suffering from mental illness. Her feast day is celebrated on May 15th.
