She was born in 1779 in Llanllechid, Caernarfonshire, Wales; her father was William Llwyd.
[1][2][3] She wrote hymns in the flyleaves (blank pages) of her Bible and other books.
[1] Pastor Thomas Levi discovered her verses and published them in the magazine Y Traethodydd in 1904.
[1][4] The hymn Dyma Feibil annwyl Iesu (This is Jesus’ Precious Bible) has been attributed to her given that it was written in her handwriting in one of her books, but the attribution is uncertain because Thomas sometimes copied down hymns from other sources.
[3] Her second husband was an elder at Gatehouse Chapel (Calvinistic Methodist) in Llanllechid, founded in 1799.
