Afrelia was a late 6th century saint, and princess of Powys. Afrelia was the daughter of Vortimer, a son of Vortigen and his queen Severa Verch Macsen (daughter of Roman Emperor Maximus). She was the wife of Umbrafel. Umbrafel had a nephew Samson of Dol. When Samson persuaded his parents to join a monastery, Umbrafel and his wife Afrelia, decided to do likewise. Afrelia was also mother of Maglor Ap Umbraphel b485–575, Henwg and another unknown child. She is said to have founded a monastery. Peter C. Bartrum suggests that she may be identical to the little-known Saint .
