The parish of Llangrove is of relatively recent formation, having been carved out of Llangarron in 1856–7. The land for the building of the church and the school was given by Mrs Marriott, the lady of the manor of Goodrich. The fact that she owned land in the centre of the village reflects the fact that the populated centre of Llangrove has been largely formed upon land which was originally a common belonging to the lord of the manor of Goodrich. Extensive encroachment settlement took place on this common, and the adjacent one of Old Grove from the 17th C onwards, though mostly in the later 18th C & 19th C. By the time of the formation of the new parish, there were many souls in need of a nearer church than the parish church at Llangarron, though there was already a non-conformist element. Long Grove and Old Grove commons were enclosed with the consent of the manor's ‘meese’ tenants after proposals were initiated in 1815.
