In his early days, while he was minister at Llanuwchllyn, Merionethshire (where he was ordained 1769), he met with a good deal of persecution and was compelled to apply to the King's Bench for a mandamus before he was allowed to conduct the services in peace.
He removed in 1777 to Haverfordwest, and thence to Drewen in Cardiganshire, 24 June 1779, where he was much beloved, and remained till his death, 3 March 1821.
His first duty here was to undo the work of his predecessor, who was in sympathy with the Arminian movement, then led by the Rev.
Evans showed great tact and gradually and successfully led back the congregation to the prevailing Calvinism of the day.
According to the same authority Evans's services to his countrymen were very great, both through the pulpit and the press.
