Annals and antiquities of the counties and county families of Wales; Section V (Old and Extinct Families of Merionethshire) (published 1872) by Thomas Nicholas the descendants of Rhodri ab Owain are described; "Thomas (ap Rhodri ap Owain), Lord of
Rhiw Llwyd, married Agnes, daughter of Einion ap Seissyllt, Lord of Mathafarn, widow of
Owain Brogyntyn, Lord of
Edeirnion. His descendants,
Lords of Rhiw Llwyd, were successively Caradog, Gruffydd, Dafydd, and Hywel, who married Efa, daughter of Ifan ap Howel ap Meredydd of Ystumcegid, of the line of Collwyn ap Tangno, founder of the fifth
noble tribe of Wales." • Tomas ap Rhodri ab Owain Gwynedd = Annest ferch Einion ap Seisyllt • Caradog ap Tomas = Efa ferch Gwyn ap Gruffudd ap Beli • Gruffudd ap Caradog = Lleuca ferch Llywarch Fychan ap Llywarch • Dafydd ap Gruffudd of Rhos = Efa ferch Gruffudd Fychan • Hywel ap Dafydd = Efa ferch Evan ap Hywel ap Maredudd • Maredudd ap Hywel (d. after 1353) = Morfydd verch Ieuan ap Dafydd ap Trahaern Goch. He had issue two sons; • Robert ap Maredudd • James (Evan) ap Maredudd According to Philip Yorke in his book
The Royal Tribes of Wales (published 1799); "The father of James and Robert was Maredudd ab Hywel ab Dafydd ab Gruffudd ab Thomas ab Rodri, Lord of Anglesey, ab Owain Gwynedd, as is evident by the Extent of North Wales, in the twenty-sixth of Edward the Third. During Robert ab Maredudd's time, the inheritance, which descended to him and his brother James, was not parted after the custom of the country, by gavelkind, but James being married -enjoyed both houses, Cefn y fan and Cesail Gyfarch. From Robert, who did not marry till near eighty, descended the houses of
Gwydir, Cesail Gyfarch, and Hafod Lwyfog; and
Sir John the historian, his descendant, says, he was the elder brother; from James ab Maredudd, who was Constable of
Cricieth, the families of Rhiwaedog, Clenenneu, Ystumcegid, Brynkir and
Park." The family who resided at
Parc came to be known as the
Anwyl of Park family, with
Anwyl taking various spellings over the years. The sons of Maredudd ap Hywel, Robert and James, took opposing sides during the last war of Welsh independence led by
Owain Glyndŵr between 1400 and c.1412. Robert, the elder brother and the ancestor of the
Wynn of Gwydir family sided with Glyndŵr but survived the war receiving a
royal pardon from
Henry IV and later by his son
Henry V. James, the younger son, opposed Glyndŵr. According to Philip Yorke he had matched his son Maredudd ab James with the daughter of Einion ab Ithel, who belonged to the House of Lancaster. James ab Maredudd held steadfastly to that house when Owain Glyndŵr rebelled so that in the time of that war he had the charge of Caernarfon town and held it for the Crown of England. In revenge for this Owain Glyndŵr burned his two houses; Cefn y fan or Ystumcegid and Cesail Gyfarch. James ap Maredudd was killed during the continuance of this war at Caernarfon and his body evacuated by sea to be buried at
Penmorfa. ==Descent from Jeuan ap Maredudd (died c.1402) to William Lewis Annwill (died 1642)==
