Dona

Saint Dona (Dwna), a holy monk, was a Welsh monk of the 6th century, a son of Selyf ap Cynan Garwyn, of the royal house of Powys. His full name was Dona ap Selyf.

After a time of monastic life at Bangor in Arfon, he withdrew as a hermit to the south-⁠east corner of the island of Anglesey. The church of Llanddona on Anglesey is dedicated to him; the first church there is said to date from around 610, and the present one was rebuilt in 1873. In the church are a bell from 1647 and a silver chalice from 1769. Near Llanddona a natural stone on the Crafgoed mountain is called "Dona's Chair", and near Knighton (Tref-⁠y-⁠clawdd) in Radnorshire there is Craig Dona, where people are said to have drunk from a healing spring. His day is 1 November, by the Western calendar (new style). He is honored as a saint of the undivided Church.
