MARC , SIARL ( 1720 - 1795 ), of Tŷ-mawr , Bryncroes , Llŷn , Calvinistic Methodist exhorter, and hymn-writer .

After his conversion about 1741 he became far and away the most important exhorter in his part of Wales . He is thought to have been a carpenter by trade. He had changed his home three or four times before settling at Tŷ-mawr farm , Bryncroes . This is what Robert Jones of Rhos-lan (q.v.) says about him in Drych yr Amseroedd : ‘ He was a man of great intelligence, strong in the true doctrine, and clearly endowed with the gifts necessary to deliver his message. He was respected in his neighbourhood and was acceptable to the churches. ’ It is not, therefore, strange that a man of his character should have won a high place in the esteem of all who knew him. In spite of his kindly nature he experienced persecution, but remained firm and unshaken and continued to preach and to supervise the societies in Llŷn . Tŷ-mawr became the meeting place of the Methodists until, in 1752 , the first Methodist chapel in Caernarvonshire was built on land adjoining the farm-house. He was blind for some years before he d., 17 May 1795 , at the age of 75. For his work as a hymn-writer see J. Thickens , Emynau a'u Hawduriaid .
