[2] The following year, a new chapel which was named Ebeneser was built near Quay Street, adjacent to a property known as Primrose Cottage.

Daniel Jones of Felinfoel supported the church in its early years, baptising three female members in February 1850 and chairing the committee which oversaw the building of the chapel.

[2] The first minister was Dafydd Morris, a native of Pembrokeshire whose pastorate included Ebeneser and Soar, Llandyfan.

[2] During these decades the population grew rapidly as Cross Inn, renamed Ammanford in the 1880s, became a major centre of the anthracite coal trade.

[2] In 1907, on completion of forty years as minister, Williams was presented with a testimonial on behalf of the congregation "as a token of their regard and deep affection".

An English Baptist Church was established at Ammanford in 1904 and finally, during the pastorate of John Griffiths, Seion, Tirydail was opened in 1913.

[1] In 1962, Garfield Eynon moved from Seion, Cwmaman, to become minister of Ebeneser and remained until his departure to Ebenezer, Aberavon, in 1975.
