Alys ferch Owain Glyndŵr
Alys ferch Owain Glyndŵr was one of the daughters of Margaret Hanmer and Owain Glyndŵr, the disinherited prince of the old Welsh royal house of Powys Fadog, who led a major revolt in Wales between 1400 and ca. 1416 against King Henry IV of England.
Little is known about any of the children of Owain Glyndŵr.
Owen Tudor
Sir Owen Tudor (1400 – 2 February 1461) was a Welsh courtier and the second husband of Catherine of Valois (1401–1437), widow of King Henry V of England.
He was the grandfather of Henry VII, founder of the Tudor dynasty.
Owen was a descendant of a prominent family from Penmynydd on the Isle of Anglesey, which traces its lineage back to Ednyfed Fychan (d. 1246), a Welsh official and seneschal to the Kingdom of Gwynedd.
Tudor's grandfather, Tudur ap Goronwy, married Margaret, daughter of Thomas ap Llywelyn ab Owain of Cardiganshire, the last male of the princely house of Deheubarth.
Margaret's elder sister married Gruffudd Fychan of Glyndyfrdwy, whose son was Owain Glyndŵr.
Owen's father, Maredudd ap Tudur, and his uncles were prominent in Owain Glyndŵr's revolt against English rule, the Glyndŵr Rising.
Catrin ferch Owain Glyndŵr
Catrin ferch Owain Glyndŵr( died 1413) was one of the daughters( probably the eldest) of Margaret Hanmer and Owain Glyndŵr, and her marriage to a claimant on the English throne was used by her father to gain support.
Gruffudd ap Dafydd Goch
Gruffudd ap Dafydd Goch was a Welsh knight of the 14th century.
He lived in Y Fedw Deg, Penmachno and was foreman of the Nantconwy jury that gave evidence to the Crown for the extent of 1352.
His stone effigy may be found in the old Church of St. Michael, Betws- y- Coed.
He was the son of Dafydd Goch, the father of Gruffudd Fychan ap Gruffudd ap Dafydd Goch and the grandfather of Gruffudd Leiaf.
Owain Glyndŵr
Owain ab Gruffydd, lord of Glyndyfrdwy (c. 1359 – c. 1415), or simply Owain Glyndŵr or Glyn Dŵr
(anglicized to Owen Glendower), was a Welsh leader who instigated a fierce and long-running yet ultimately unsuccessful war of independence with the aim of ending English rule in Wales during the Late Middle Ages.
He was the last native Welshman to hold the title Prince of Wales ("Tywysog Cymru").
Glyndŵr was a descendant of the Princes of Powys through his father Gruffudd Fychan II, hereditary "Tywysog" of Powys Fadog and Lord of Glyndyfrdwy, and of those of Deheubarth through his mother Elen
ferch
Tomas
ap Llywelyn ab Owen.
On 16 September 1400, Glyndŵr instigated the Welsh Revolt against the rule of Henry IV of England.
The uprising was initially very successful and rapidly gained control of large areas of Wales, but it suffered from key weaknesses – particularly a lack of artillery, which made capturing defended fortresses difficult, and of ships, which made rebel-controlled coastlands vulnerable.
The uprising was eventually suppressed by the superior resources of the English.
Glyndŵr was driven from his last remaining strongholds in 1409, but he avoided capture; the last documented sighting of him was in 1412.
He twice ignored offers of a pardon from his military nemesis, the new king Henry V of England, and despite the large rewards offered, Glyndŵr was never betrayed to the English.
His death was recorded by a former follower in the year 1415.
With his death
Owain acquired a mythical status along with Cadwaladr, Cynan and Arthur as a folk hero awaiting the call to return and liberate his people.
In William Shakespeare's play "Henry IV, Part 1", the character of Owen Glendower is a wild and exotic king ruled by magic and emotion.
In the late 19th century, the Cymru Fydd movement recreated him as the father of Welsh nationalism.
Kaya Alp
Kaya Alp was, according to Ottoman tradition, the son of Kızıl Buğa and the father of Suleyman Shah, who was, in turn, the grandfather of Ertuğrul, and the great grandfather of the Ottoman Empire founder, Osman I.
Maredudd ab Owain Glyndŵr
Maredudd ab Owain Glyndŵr was a son of Margaret Hanmer and Owain Glyndŵr.
He was the last significant active participant in the revolt raised by Glyndŵr in Wales between 1400 and c. 1416.
Alis Wen
Alis ferch Gruffudd ab Ieuan ap Llywelyn Fychan or Alis Wen(" Alice the White"; 1520 –?) was a poet who wrote in Welsh.
She was the daughter of Gruffudd ab Ieuan ap Llywelyn Fychan( 1485 – 1553) of Llannerch and Sioned ferch Rhisiart ab Hywel of Mostyn( died 1540).
Her two sisters, Catrin and Gwen, were also poets.
Alis composed series of" englynion" discussing the kind of husband she wished to marry and commenting on her father's second marriage in old age, and a" cywydd" to reconcile Dafydd Llwyd Llydan and Grigor y Moch.
She married David Lloyd ap Rhys of Vaynol in about 1540.
They had four children:
Ieuan ab Owain Glyndŵr
Ieuan ab Owain Glyndŵr was reputedly the illegitimate son of the last native Welsh Prince of Wales; Owain Glyndŵr.
The possibility of his existence was uncovered through the work of Peter Bartrum which is currently being edited by the University of Wales Aberystwyth.
Ieuan ab Owain and his descendants are detailed in" Peniarth Manuscript 287" in the hand of Robert Vaughan of Hengwrt( c.1592-1667) and also in the manuscript known as" Harley 1969" by Griffith Hughes( 1634 – 1665)- the original manuscripts are kept at the National Library of Wales, Aberystwyth and the British Library respectively.
Ieuan, who is thought to have been born around 1380 and to have died around 1430, is thought to have had three sons:
Gruffudd ab Owain Glyndŵr

the disinherited Prince of the old Royal house of Powys Fadog who led a major revolt in Wales between 1400 and c.1416.
