Aodhnait or the earlier form Ednat is the feminine version of the name Edá, which would later become Aodhá or Aidan. Edana is a more modern version of the feminine name.
St. Edana (also known as Edna and Eidyn) lived near the Boyle and Shannon Rivers in the sixth century. Her name given to her by St. Patrick translates to “little fire.”
She would eventually travel to Scotland and found a convent there. It is now believed that the capital of Scotland was named after this Irish nun. Edinburg or “Dún Édana” means “Edana’s castle” or “Edana’s fortress.”
Her feast day is celebrated on July 5. Most consider her the Saint of New Tuamia, in the diocess of Elphin, and also of Tuam. A holy well was named after her as well as other points in Western Ireland. She is often confused with Saint Modwenna, and some believe them to be the same person.
