Llangarron is a small village and civil parish in southwest Herefordshire within seven miles of Ross-on-Wye ( Herefordshire, England) and Monmouth ( Monmouthshire, Wales). The population of the Civil Parish at the 2011 census was 1,053. The church is dedicated to St. Deinst. The village no longer has a post office nor pub, though it does have a hall. The civil parish includes the settlements of Llangrove, Llancloudy and Three Ashes.
The name (also spelt Llangarren and Llangarran) refers to the Garron Brook, a tributary of the River Wye. Several local farms have Welsh names, a legacy of the fluid nature of the England-Wales border in the past. An alternative view is that the village is named after the Welsh word “garan” which means heron, stork or crane. This may explain the representation of such a bird in the church gates.
'St Deinst' appears nowhere else in England. It is identified with St. Deiniol, or Deiniel, a sixth-century abbot-bishop who founded a monastery at Bangor and to whom the mediaeval Bangor Cathedral was dedicated. Records of a church at Llangarron go back as far as Edward the Confessor, when a wooden ecclesiastical building was consecrated under the heirs of Ceheric ap Eleu, and was then reconsecrated under William I as "lan garan" church.
