The name "Gwbert" is thought to derive from a Celtic dedication (i.e. St Cubert), suggesting that a chapel may have existed here at one time. Gwbert, a wandering saint, is said to have landed here and sheltered in a cave. In fact Gwbert is among a group of five Saints (the others being Pedrog, Briog, Carannog and Meugana) honoured in church dedications near the mouth of the river Teifi, and also in churches lying in close proximity to each other in mid-Cornwall, and then again in neighbouring churches in Brittany.
