In 1990 this plaque was installed on the outside of the current farmhouse at Gellilwcafach Farm by descendants of former residents of the farm: Noah Williams and family members. They had emigrated to America as converts to The Church of Jesus Christ of Latter Day Saints (often referred to as 'Mormons') in 1875. The plaque was removed some years ago when the outside render of the house was re-newed, and has not been re-installed.
