The `Llwyn' family is descends through Wiliam Wyn, Glyn Cywarch, in Merioneth, from Osbwrn
Wyddwalch (often heard as Osbwrn Wyddel), one of the ancestors of the Wynns of Penniarth and
many other families. They descend also through Cathrin, wife of this William Wyn, who was the daughter of William Lewis Anwyl, of Parc, Llanfrothen; from the prince Owain Gwynedd, son of
Prince Gruffydd ap Cynon, a descendant of Rhodri Mawr. They have an old connection with the
Nanneys through Gwenllian, daughter of the said Gruffydd ap Cynon, because this family comes
from Cadwgan ap Bleddyn ap Cynfyn, prince of Powys. Apart from this there is a connection because
Elis, 3rd son of William Wyn and Cathrin, married, on 4th January 1639, Lowri, daughter and heiress
of Edward Thomas ab John of Cwm Nantcol, who was brother of the noted John Jones, who was born
in Cwm Nantcol, a descendant of the Nanney family, who married a daughter (should be sister) of Oliver Cromwell. John Jones was one of those who signed Charles I death warrant.
A nephew to Elis and Lowri was Rev Elis Wyn of Lasynys, (whose second wife was Lowri Llwyd of
Hafod Lwyfog), the famous author called `Y Bardd Cwsg'. Lowri, a daughter, married Rev John
Hughes, minister at Llandanwg and Llanbedr near Harlech. Their daughter, Ann, married John
Hartley (brother of Robert Owen, or in full Robert Hartley Owen, grandfather of Mr Reveley,
presently of Bryn y Gwin). They went to live at Gyffyllog Island, in the parish of Llangelynin.
Thomas Hartley, 2nd son of the last named, who became Deputy Lieutenant for Merioneth, married
Mary Nannau, daughter of Rev Robert Nannau of Llwyn. They were parents of the late Anne Hartley
of Llwyn and also Mary, wife of Gruffydd Williams, solicitor, parents of Thomas Humphrey
Williams of Llwyn, JP for Merioneth.
This Thomas Humphrey Williams, and two sisters, are still living and brothers are Robert Nannau
Williams and Meurig Meredydd Williams, the latter a doctor.
As has been said, Elis was 3rd son of William Wyn and Cathrin and was husband of Lowri. William
Lewis Anwyl was a son of Lewis Anwyl and Elizabeth, daughter of Morys ab Ifan, Plasynywern.
Lewis anwyl was a son of Robert ab Morys, of Parc, and Lowri, daughter of Lewis ab Ifan ab Dafydd
and his wife Catrin, daughter of Meredydd ab Ifan ab Robert of Gwydyr. Robert ab Morys was a son
of Morys ab Sion ab Meredydd and Angharad, daughter of Elisau (Elis) ab Gruffydd ab Finion.
This Morys ab Sion ab Meredydd was son of Sion ab Meredydd and Gwenhwyfar, daughter of
Goronwy ab Ifan of Collwyn.
Sion ab Meredydd was son of Meredydd ab Ifan and Angharad, daughter of Eirion ab Ithel, heiress of
Rhiwaedog. Meredydd ab [fan was son of Ifan ab Meredydd and Lleuci (Lucy), daughter of Hywel Sele of
Nannau.
Ifan ab Meredydd was son of Meredydd ab Hywel and Morseydd, daughter of Iorwerth Goch ab
Dafydd ab Trahaiarn. Meredydd ab Hywel was son of Hywel ab Dafydd and Eta, heiress of
Ystumcegid, daughter of Ifan ab Hywel ab Meredydd. Hywel ab Dafydd was son of Dafydd ab
Gruffydd and Anne (or according to another source, Efa) (not possible to follow line in detail),
daughter of Gruffydd Fychan ab Moriddig. Dafydd ab Gruffydd was son of Gruffydd ab Cariadog
and Lleuci (Lucy), daughter Llywarch Fychan ab Llywarch. Gruffydd ab Cariadog was son of Cariadog ab
Thomas and Eva, daughter of Gwyn (or Cynon) ab Gruffydd (ab Beli according to another source).
Cariadog ab Thomas was son of Thomas ab Rhodri, and Annes (or Marged), daughter Einion ab
Seisyllt. Thomas ab Rhodri was son of Rhodrian Ywain Gwynedd and Annes (Agnes in another
source), daughter of Lord Rhys. Rhodri ab Ywain was son of Ywain Gwynedd and Christian,
daughter of Goroanwy ab Ywain ab Edwyn. And Ywain Gwynedd was son of Gruffydd ab Cynon
and Angharad, daughter of Ywain ab Edwyn.
Then follows a praise poem following the death of Robert son of Morus ab Sion ab Merdydd of Parc,
composed by William of Lleyn.
Note:
The patronymic ap is given as ab above although this latter should be the case only before a vowel
- ab Ifan but ap Goronwy etc.
A footnote to the article says that the other source mentioned is in table i. yn the History of the
Gwydir family published in 1878 but there are some areas where things are not too clear.
