 Richard Davies' lyric may have been influenced by the 14th Century love story of Myfanwy Fychan of Castell Dinas Brân, Llangollen, and the poet Hywel ab Einion(*2).That story was also the subject of the popular poem, "Myfanwy Fychan" (1858), by John Ceiriog Hughes (1832–87).Some sources say it was written with Parry's childhood sweetheart, Myfanwy Llywellyn, in mind (*3).
