one of the foremost leaders of the Welsh Calvinistic Methodist revival, along with Howell Harris and William Williams. For most of his life he was curate in the parishes of Nantcwnlle and Llangeitho, Ceredigion. He was renowned as a preacher and made Llangeitho memorable as a centre for Calvinistic Methodism in Wales. His date of birth was traditionally given as 1713 but more recent research indicates 1711. The Anglican Church authorities deprived him of his Nantcwnlle curacy in c. 1763, an action which was unpopular with parishioners. Following this, he established a Methodist "cause" in Llangeitho.
