Eglwys Llantrisant

Its parish church is dedicated to Saints Afran, Ieuan, and Sanan.^[3] The parish's former church is now a protected building. Browne Willis^[4] and Sabine Baring-Gould^[5] 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".^[5]) 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.^[4]
