Its parish church is dedicated to Saints Afran, Ieuan, and Sanan.[2] The parish's former church is now a protected building. Browne Willis[3] and Sabine Baring-Gould[4] considered "Afran" to be a corruption of Afan, a saint of Ceredigion and Brecknockshire. (The 16th-century Peniarth MS 147 concurs, listing the church as dedicated to "Sannan and Afan and Evan".[4]) St Afan was related to the Cuneddan dynasty of Gwynedd and was claimed as an ancestor by a 10th-century Ieuan martyred by Viking raiders.[3]
