Title: Dafydd ap Llywelyn
Content:  Though birth years of 1208, 1206, and 1215 have been put forward for Dafydd, it has recently been persuasively argued that he was born shortly after Easter 1212. Born at Castell Hen Blas, Coleshill, Bagillt in Flintshire, he was the only son of Llywelyn the Great by his wife, Joan (daughter of King John). His grandfather was facing trouble in England against his Barons when he was born. In his final years, Llywelyn went to great lengths to have Dafydd accepted as his sole heir. By Welsh law, Dafydd's older half-brother Gruffydd had a claim to be Llywelyn's successor. Llywelyn had Dafydd recognised as his named heir by his uncle King Henry III in 1220, and also had Dafydd's mother Joan declared legitimate by the Pope to strengthen Dafydd's claim.
Title: Dafydd ap Dafydd ap Llywelyn
Content:  According to early modern genealogist Lewys Dwnn, Dafydd ap Dafydd ap Llywelyn  was the illegitimate son of Dafydd ap Llywelyn, Prince of Wales and King of Gwynedd between 1240 and 1246. He is considered the ancestor of the Prys or Price of Esgairweddan family, who bore the royal arms of Gwynedd as their own. It is generally considered that this family, in the direct male line descent, died out on the death of Robert Price of Esgairweddan in 1702. Dafydd ap Dafydd ap Llywelyn was presumably a minor when his father, the prince, died in 1246 and was unable to contest the throne of Gwynedd which was claimed by Owain Goch and his brother Llywelyn ap

Title: Dafydd Llwyd ap Llywelyn ap Gruffudd (Dafydd Llwyd o Fathafarn)
Content:  Dafydd Llwyd ap Llywelyn ap Gruffudd, usually referred to as Dafydd Llwyd o Fathafarn (fl. c.1400–c.1490) was a Welsh language poet, a native of Mathafarn, Powys. The bulk of Dafydd Llwyd's surviving poetry is characterised by his hopes and aspirations for a Mab Darogan (‘Son of Prophecy’) who would throw off the yoke of English rule and realise the restoration of an independent Wales. He was recognised as the leading authority on the prophetic lore and traditional history of Wales and was widely consulted. Like other prophetic poets of his period, Dafydd attached his hopes initially on Jasper Tudor, Earl of Pembroke, and then on his nephew Henry Tudor. Following his success at the Battle of Bosworth Dafydd composed poems in praise of Henry, his son Arthur and to Sir Rhys ap Thomas, their leading Welsh supporter and advisor. He also composed a number of erotic poems, notably a poetic disputation with the poet Gwerful Mechain, as well as religious and secular praise poems.
Title: Llywelyn ap Dafydd
Content:  Llywelyn ap Dafydd (c.1267&ndash;1287), potential claimant to the title Prince of Gwynedd, was the eldest son of Dafydd ap Gruffydd, the last free ruler of Gwynedd, and his wife Elizabeth Ferrers. Nothing is known of his early life, though it is thought he was probably born some time around 1267. It is likely he accompanied his father during periods of exile in England in the 1270s. Following the death of Llywelyn ap Gruffudd on 11 December 1282 the governance of Gwynedd was placed in the hands of Llywelyn's successor, his brother, Dafydd ap Gruffudd. Dafydd and his son Owain were captured together at Nanhysglain near to Bera Mawr in the uplands above Abergwyngregyn on 21 June 1283. King Edward I of England then issued orders for the apprehension of the primogeniture of Dafydd ap Gruffudd. On 29 June, Llywelyn ap Dafydd was

(1596), Dr David Powel, Siôn Huws of Maes y Pandy, near Talyllyn, and also some Ymrysonau (bardic debates) between himself and Roger Cyffin (and also with Lewys Dwnn).

Dafydd Ist had a nemesis in his nephew Llywelyn ap Iorwerth,  who was born most likely in the year 1173 and therefore only a child when all these events played out. Llywelyn's father Iorwerth Drwyndwn had been involved in the early stages of the dynastic struggles and most likely died sometime around 1174, during the same time as the usurpation of Dafydd I. As the century drew to a close Llywelyn became a young man and decided to stake his

Dafydd succeeded Llywelyn as prince of Gwynedd, but King Henry was not prepared to allow him to inherit his father's position in the remainder of Wales. Dafydd was forced to agree to a treaty greatly restricting his power and was also obliged to hand his half-brother Gruffydd over to the king, who now had the option of using him against Dafydd. Gruffydd was killed attempting to escape from the Tower of London in 1244. This left the field clear for Dafydd, but Dafydd himself died with illegitimate and underage issue in 1246 and was eventually succeeded by his nephew, Gruffydd's son, Llywelyn ap Gruffudd.
Title: Dafydd ap Llywelyn
Content:  There was considerable support for Gruffydd in Gwynedd. Although Dafydd lost one of his most important supporters when his mother died in 1237, he retained the support of Ednyfed Fychan, the Seneschal of Gwynedd who wielded great political influence. Llywelyn suffered a paralytic stroke in 1237, and Dafydd took an increasing role in government. Dafydd ruled Gwynedd following his father's death in 1240. Although Henry III had accepted his claim to rule Gwynedd, he was not disposed to allow him to retain his father's conquests outside Gwynedd. As the diplomatic situation deteriorated, Dafydd began to explore alliances with others against Henry, and is known to have sent ambassadors
