The controversial Iolo Manuscripts claim an older foundation dating to Saints Dyfan and Fagan, said elsewhere to have missionized the court of KingLucius of Britain on behalf of PopeEleutherius around 166. The manuscripts—others of which are original and others now known forgeries—list Dyfan as the first bishop and, following his martyrdom, Fagan as his successor. Baring-Gould refers to them as chorepiscopi. The present-day St Fagans is now a village near Cardiff. Originally Celtic Christians, the bishops were in full communion with the Roman Catholic Church from 777 until the Reformation. In AD 914, the Danes ravaged Archenfield, according to the Anglo-Saxon Chronicle. The jarls leading the raids, Ohtor and Hroald, captured the bishop; he was later ransomed. The jarls were killed in a subsequent battle at "Killdane Field" in Weston-under-Penyard and the raiders were subdued. The first evidence that the bishops were called Bishop of Llandaff is from the early 11th century. Before this, though still ministering to Glamorgan and Gwent, the bishops described themselves as Bishop of Teilo and were almost certainly based at Llandeilo Abbey. The very early bishops were probably based in Ergyng. Before 1107, the title Bishop of Gwlad Morgan had been adopted. It was not until the title Bishop of Llandaff was used by Bishop Urban from. In medieval records, the bishop was sometimes referred to as the Archbishop of Llandaff. This appears to have been a simple reaction to the claim of St David's to the archiepiscopal title. In 1534, the church in England and Wales broke allegiance with the Roman Catholic Church and established the Church of England. After a brief restoration with the Holy See during the reign of Queen Mary I, the Welsh dioceses remained part of the Anglican Province of Canterbury from the reign of Queen Elizabeth I until the early 20th century. Following the passing of the Welsh Church Act 1914, the church in Wales and Monmouthshire was disestablished and the independent Church in Wales was created on 31 March 1920. The bishopric and diocese of Llandaff now constitute part of the Church in Wales within the wider Anglican Communion. In 1924, the Dahlia 'Bishop of Llandaff' was named after Joshua Pritchard Hughes, who was bishop from 1905 to 1931. The most recent bishop of Llandaff was Barry Morgan; when elected as bishop in 1999 his official signature was Barry Landav, but once elected Archbishop of Wales in 2003 his archiepiscopal signature Barry Cambrensis took precedence. He was supported by David Wilbourne, assistant bishop of Llandaff. On 27 April 2017, it was announced that June Osborne will become bishop of Llandaff following Morgan's retirement; the confirmation of her election has been scheduled for 14 July 2017.
