Chapelry of St Bruno Attendance - no service "The Chapelry is in a mountainous district amidst a thinly scattered population. When the weather is inclement there is no attendance, or but a very thin one, at Church. It is impossible to give exact information. The people follow Dissent. ..............."

"CARNGIWCH (CARN-GIWG), a parish in the hundred of GAFLOGION, county of CARNARVON, NORTH WALES, 5 miles (N.) from Pwllheli, on the road from Carnarvon, containing 117 inhabitants. This parish, which is situated near the river Erch, takes its name from a lofty conical hill, called Moel Carn Giwch, on the summit of which is a vast heap of loose stones, generally thought to be a carnedd, but said by popular tradition to have been thrown down by a giantess, who carried them thither in her apron. The living is a perpetual curacy, annexed to the rectory of Edern, in the archdeaconry and diocese of Bangor. The church, dedicated to St. Ciwg, or St.Beuno, and in which divine service is performed only every third Sunday, is a small neat edifice, rebuilt, with the exception of the east end, in 1828. The average annual expenditure for the support of the poor is £48. 8. " A Topographical Dictionary of Wales by Samuel Lewis, 1833
