Amwn Ddu

Venerable Amwn Ddu (Amwn the Black) was a son of Emyr Llydaw and the father of Saint Samson of Dol, who died between 567 and 570. He left the district of Vannes in Brittany, where Britons had settled, married Anna, daughter of Meurig, and is said to have enjoyed the friendship of Saints Dyfrig and Illtyd. When he fell gravely ill, his son Samson, a monk at Llantwit, came to see him; Amwn confessed a serious sin and vowed to give the rest of his days to God. Anna also offered her children to the monastic life. Samson took Amwn with him to Ynys Byr, then to a wild place near the Severn, and at Southill in Cornwall he left him in charge of the monastery.

Welsh sources say Amwn was buried at Llantwit Major. At Plescop near Vannes an Amon is venerated, with his skull kept in a reliquary bust; the link with Amwn Ddu is only a conjecture. Amwn Ddu is a saint of the undivided Church.
