The village is linked with
Daniel Rowland, born here in 1713, and the
Welsh Methodist revival in the 18th century. Rowland served as
curate at Llangeitho and
Nantcwnlle. The village chapel, built in 1760, became famous throughout Wales as a
Calvinistic Methodist centre. Thousands visited it to hear the preaching. Rowland was buried in the village and there remains a memorial column to him. Larger replacement chapels were built in 1764 and 1814. Llangeitho saw several further periods of religious revival in that century, the strongest in 1762, when rejoicing, dancing and jumping for joy earned the Welsh Methodists the nickname "Jumpers".
