Gruffudd ap Cynan
Gruffudd ap Cynan (c. 1055 – 1137), sometimes written as Gruffydd ap Cynan, was King of Gwynedd from 1081 until his death in 1137.
In the course of a long and eventful life, he became a key figure in Welsh resistance to Norman rule, and was remembered as King of all Wales.
As a descendant of Rhodri Mawr, Gruffudd ap Cynan was a senior member of the princely House of Aberffraw.
Through his mother, Gruffudd had close family connections with the Norse settlement around Dublin and he frequently used Ireland as a refuge and as a source of troops.
He three times gained the throne of Gwynedd and then lost it again, before regaining it once more in 1099 and this time keeping power until his death.
Gruffudd laid the foundations which were built upon by his son Owain Gwynedd and his great-grandson Llywelyn the Great.
Cadfan ap Cadwaladr
Cadfan ap Cadwaladr, Lord of Ceredigion( c. 1140- c. 1215) was the elder son of Cadwaladr ap Gruffydd, the brother of Owain Gwynedd, King of Gwynedd and overlord of all Wales.
His mother was his father's first wife, Gwerfel ferch Gwrgan.
He was probably born in Ceredigion, where his father held extensive estates.
His father was banished in 1144.
He should not be confused with Cadell ap Gruffydd, King of Deheubarth, who took Ceredigion from Hywel ab Owain Gwynedd, son of Owain Gwynedd, in 1150.
Cadfan probably spent the rest of his life in exile in England.
He married Gwenllian, a daughter of Owain Cyfeiliog.
He is known to have had only one daughter: Tangwystl ferch Cadfan( born c. 1212).
Obata Toramori

Gweirca ferch Owain
Gweirca ferch Owain( possibly Gwerica) was a medieval Welsh noblewoman, granddaughter of Madog ap Gruffydd Maelor and daughter of Owain ap Gruffydd ap Madog.
Idwal Iwrch
Idwal Iwrch, or Idwal ap Cadwaladr, is a figure in the genealogies of the kings of Gwynedd.
He was the son of King Cadwaladr ap Cadwallon( reigned c. 655 – 682) and the father of King Rhodri Molwynog( died 754).
William Wynne places Cynan Dindaethwy as his son, but other sources have Cynan as the son of Rhodri.
The records of this era are scanty, and Idwal's name appears only in the pedigrees of later kings and in a prophecy found in two 14th- century Welsh manuscripts, which says that he will succeed his father Cadwaladr as king.
The only mention of Idwal Iwrch in the historical record is the appearance of his name in genealogies such as those from Jesus College MS. 20( as the father of" Rhodri Molwynog son of Idwal Iwrch son of Cadwaladr Fendigiad") and the Harleian genealogies( as the father of" Rotri son of Intguaul son of Catgualart").
John Davies'" History of Wales" does not mention Idwal, while John Edward Lloyd's" History" says only that Idwal was Rhodri Molwynog's father.
The King of Gwynedd during Idwal's lifetime is not known, and while he is one of the most likely candidates( because he was both the son of a king and the father of a king), there is no sufficiently reliable basis to either assert or deny it.
Idwal's name appears in the" Dialogue between Myrddin and his sister Gwenddydd", a Middle Welsh vaticinatory poem whose text is preserved in two medieval Welsh manuscripts, Peniarth 3( c. 1300) and the Red Book of Hergest( c. 1380- 1410).
In the text's question- answer form, a succession of" future" kings is prophesied, with Idwal among them.
This succession agrees with the historical genealogies from father to son, but does not agree with the known royal succession.
