There was acrimony at Mynydd-bach Independent (Congregational) church in 1839 that led to a split. The minister together with the majority of the congregation left the chapel to set up their own i.e. Caersalem Newydd Baptist Chapel.

The minister was a drunk, a rogue and a confidence trickster who eventually was whipped and imprisoned.

There are numerous maps, leaflets, photographs and information about the people and places, fabric of the chapel as well as details of ministers since the beginning up to the present time.
