[1][2][3] The church (dedicated to Gwenllwyfo, a 7th-century woman about whom nothing else is known) was a chapel of ease attached to the parish of Amlwch, about 5 miles (8 km) away.

[6] In 1812, the priest responsible for the church was Edward Hughes, whose wife was the niece of the owner of Llys Dulas, the landed estate in the area.

The screen had inscriptions in Welsh and Latin, and a note that "Richard Williams of Rhodogeidio who married Marcelly Lloyd at his own charge caused all this worke to be don to the honor of God and his church".

[7] At the time of a survey by the Royal Commission on Ancient and Historical Monuments in Wales and Monmouthshire in 1937, although the building was in bad condition with an insecure roof, it still retained an 18th-century oak communion table, a rectangular font dating from the 12th century, the 1610 screen (damaged), the pulpit, fragments of an oak sounding board (also dated 1610) and some 18th-century memorials.

[9] The antiquarian Angharad Llwyd described the church in 1833 as "a small neat edifice, appropriately fitted up for the performance of divine service".

[4] Samuel Lewis, writing in the middle of the 19th century, said that the church was "a conspicuous and interesting object" in a parish that "partakes much of the general character of dreary sterility by which the mining districts in the immediate vicinity are distinguished".

[10] However, the clergyman and antiquarian Harry Longueville Jones, writing in 1859 about the church as it had been 15 years earlier, said that "the whole building was in bad repair".
