Sadwrn

Saint Sadwrn (Sadwen) was a hermit of Wales in the sixth century, brother of Saint Illtud and disciple of Saint Cadfan. A number of churches in Wales are dedicated to him.

Welsh tradition knows two saints of this name, one of Llansadwrn near Beaumaris in Anglesey and one of Henllan in Denbighshire; a burial stone from AD 550 at the latest suggests that the first may also have been called Sadyrnin (Saturninus). The Orthodox calendar does not say which of them is commemorated. He is a saint of the undivided Church and is commemorated on 29 November (New Calendar).
