In her youth, with the help of a few friends, she published a short-lived periodical called Home Sunshine, which was printed at Newcastle Emlyn. In 1894 she shared a prize offered at the Caernarvon national eisteddfod for a serial dealing with Welsh life, and this was later published in the North Wales Observer under the title ‘Ynysoer.’ In June 1896 she finished writing a novel called ‘Mifanwy,’ but having had it rejected by six publishers, she changed the title to ‘A Welsh Singer, by Allen Raine.’ She dramatised this novel, but it was only performed on one occasion. After this she produced one novel after another in quick succession, Torn Sails, 1898; By Berwyn Banks, 1899; Garthowen, 1900; A Welsh Witch, 1902; On the Wings of the Wind, 1903; Hearts of Wales, 1905; and Queen of the Rushes, 1906 (which depicts a number of incidents of the religious revival of 1904 and 1905). Published posthumously were Neither Store-house nor Barn, 1908 (which had already appeared in serial form in the Cardiff Times); All in a Month, 1908 (treating of her husband's malady); Where Billows Roll, 1909; Under the Thatch, 1910 (dealing with cancer, from which the author died). In 1909 there was published An Allen Raine Birthday Book. She contributed a number of short stories to various periodicals, and in Wales, 1897, vol. iv, there appears an English translation by her of Ceiriog's poem ‘Alun Mabon.’
