Saint Rhain Dremrudd

Rhain Dremrudd (Reginus in Latin and Reginald in English; fl. 5th century) was the eldest son of Brynach Brycheiniog, whom he succeeded on the throne of Brycheiniog, an early medieval Welsh kingdom. He was born around 442. Little is known of his reign, but it is certain that he was a warrior king who expanded his territory. He died in the late 5th century and was buried at Llandyfaelog Fach. He was succeeded by his son Rhigeneu. He should be identified with Rhein the Generous, the maternal grandfather of Saint Asaph.
