1776-1805. Welsh hymnwriter. Born Ann Thomas, she joined the Methodist society at Pontrobert in 1797 after experiencing evangelical conversion. She married John Griffiths of Meifod in 1804 and died the following year after the birth of a child. She was in the habit of composing hymns which she recited to her servant, Ruth Evans, who later married Methodist minister John Hughes. Between them they preserved and published the hymns of [[Ann Griffiths]], comprising a remarkable literary phenomenon characterized by a masculine strength, complex biblical allusions, and a profound Christocentric mysticism.
