Tudwen

Saint Tudwen was a Welsh holy woman of the 5th century. According to the traditional genealogies, she was one of the many children of Brychan, king of Brycheiniog. Little is known of her apart from her place in these genealogies and the fact that she is the founder and patron of the church of Saint Tudwen at Llandudwen (community of Buan) in the Llŷn peninsula, Gwynedd.

Near the church, in a field, was the spring Ffynnon Dudwen, dedicated to the saint, which is no longer there today. Its water was used to baptize the children of the parish, and it was credited with healing epilepsy, rheumatism, numbness of the body and tired eyes. It is also recorded that secret marriages were blessed near it. Her day is 21 or 27 October, by the Western calendar (new style). She is honored as a saint of the undivided Church.
