After Jones and other members of the congregation were imprisoned in Carmarthen in 1660, they met in a cave on Craigyrwyddon, while the first chapel was built c.1689 after the passing of the 1688 Act of Toleration. In 1740 a part of the congregation split off to form the cause at Pentretygwyn (NPRN 6473), the Cefnarthern congregation moving towards Arminianism, the Pentretygwyn cause towards Calvinism. According to Rees & Thomas (Hanes Eglwysi Annibynnol Cymru) the cause declined after the split and the chapel was at some point used by the Baptists. In 1772 Cefnarthen and Pentretygwyn were reunified, with a meeting on ministers on August 18th of that year, the expenses for which were underwritten by Pentretygwyn."

William Williams ("Pant-y-celyn," after a farm where he lived), the Welsh Methodist revival hymnodist and preacher (1717-1791), is buried in the churchyard of St. Mary's in Llanfair, but his father John was an elder at Cefn arthen.
