Paul Aurelian was a 6th-century Welshman who became first bishop of the See of Léon and one of the seven founder saints of Brittany. He allegedly died in 575, rumoured to have lived to the age of 140, after having been assisted in his labors by three successive coadjutors. This suggests that several Pauls have been conflated. Gilbert Hunter Doble thought that he might have been Saint Paulinus of Wales.

Saint Teilo, also known by his Cornish name Eliud, was a British Christian monk, bishop, and founder of monasteries and churches. He was from Penalun (Penally) near Tenby in Pembrokeshire, south Wales.
