Myfanwy is a bit of an enigma. I concur with the details on the Radnorian website.
A Poet of Merit she translated Three Sketches of Life in Iceland, published in 1877 (the book is dedicated to HBH Princess of Wales and St. Lawrence Orphanage, (which was dedicated to Baroness Mohrenheim, wife of the Russian Envoy in Cophenhagen), published in Copenhagen in 1874. Other known works include Sir Howel; A Legend of Radnorshire, with Other Poems and Translations, published in 1863.
She does not appear on the 1841 census with her family, albeit she would be approaching 16 years of age, but she does appear on the 1851 census records Myfanwy at Glyn-y-Mel, home of uncle John Fenton where she is recorded as a Governess.
You can glean many clues from her poems and epigrams:- Farewell to Glyn-y-Mel, My Sister Margaretta's Birthday (dated 25th May 1853), In Memoriam. To the memory of Maria Thomas, daughter of the Rev. Watkin Thomas, B.D., who died of consumption at Cwm Dinas, Pembrokeshire, aged 17, 1848., To the Memory of my Father, Written by the Severn, at Shrewsbury (where she wrote about her yearning of Glyn-y-Mel), On the Difference Between my Sister's Verses and Mine, Margaretta, On John, Our Fishguard Postman and On My Cousin's Procrastination, To My Cousin William, On a New Lock Invented by my Uncle, To my Cousin after a Long Silence and An Invitation to Tea, where once again she mentions Glyn-y-Mel, the "honeyed retreat"
The Ghost of Sawel - Pen-y-Cil, respectfully dedicated to her uncle and the other members of the South Wales Local Committee of the British Archcealogical Society for the year 1852, mentions her cousin William again.
On the 1st September 1863 there is a prologue to the play of "The Seasons", where she records something spoken by one of her pupils at Norton House.
Lines, was written by Myfanwy at 12 years of age on the 'Farewell of one of her Governesses'.
Her Acrostics mention William George Owen, Elizabeth Foley, Jane Foley and John Foley, presumably friends from her days at Glyn-y-Mel.
Although the date is unknown, she was asked 'to write something, whilst in the midst of a party who were listening to an aeolian harp in an old ruin situated in the grounds of Haardt Schlossen Rheinpfalz, Bavaria'.
In July of 1863 she is residing in Rotterdam, from where she wrote a "Letter to Landau", it can only be assumed that this is Landau, Bavaria as she was a pupil at The Institute of Madame Reichard.
It is unknown where and when she died but it was after 1877.
