Llanfyllin is a tiny market town, neighborhood and selecting ward in a sparsely-populated area in Montgomeryshire, Powys, Wales. Llanfyllin's population in 2011 was 1,532, of whom 34.1% could talk Welsh. Llanfyllin indicates church or parish (llan) of St Myllin ('m' often mutates to 'f' in Welsh). The community hinges on the valley of the River Cain near the Berwyn Mountains in Montgomeryshire, 14 miles (23 kilometres) southwest of Oswestry and also 15 miles (24 km) from Montgomery. The River Cain is joined by the little River Abel in Llanfyllin (most likely named after Cain and Abel in the Bible), as well as twists with the valley, moving right into the River Vyrnwy at Llansantffraid. The community lies in between Shrewsbury as well as Bala, for a long time the crucial market communities in this area of Wales as well as the Welsh borders. At nearby Bodyddon there is proof of an early British settlement. Llanfyllin may be the "Mediolanum among the Ordovices" described in Ptolemy's Location (c.? advertisement 150), although others argue for Meifod or Caersws. The community is understood for its holy well, Fynnon Coed y Llan. The well is devoted to Saint Myllin, that is deemed to have actually baptised individuals right here in the sixth century. The parish church is additionally committed to Saint Myllin. There is a practice that Saint Myllin is the Irish bishop, Saint Mo Ling (likewise named Moling Luachra) (614-- 697). Nonetheless, this doubts. There is no document of Mo Ling taking a trip to Wales, as well as there is a tradition that Myllin is buried under the church of Llanfyllin church whereas Mo Ling is believed to have been buried at his abbey in Ireland.
