There are places of worship for Independents and Methodists. Poor children of this parish are eligible to the free school at Criccieth, founded by the Rev. David Ellis. The average annual expenditure for the relief of the poor amounts to £ 19. 13. (A Topographical Dictionary of Wales by Samuel Lewis, 1833)
