Beli ap Eiludd
Beli ap Eiludd was a 7th-century King of Powys.
Some theories assert that he was in fact the son of Manwgan ap Selyf who regained power after Eiludd Powys was killed at the battle of Battle of Maes Cogwy in 642.
It is more likely however that as the genealogies state he was the son of Eiludd who was either the son or brother of Selyf,
the former being the most likely due to a surviving reference from Cynddelw painting the Mathrafal dynasty as being descendants of Selyf.
It was also likely if Eiludd Powys fought at Maes Cogwy alongside Elfan Powys and Cynddylan, Beli would have been the King whom Heledd ran to for protection.

Iago ap Beli
Iago ap Beli( c. 540 – c. 616) was King of Gwynedd( reigned c. 599 – c. 616).
Little is known of him or his kingdom from this early era, with only a few anecdotal mentions of him in historical documents.
Iago ap Beli( Latin: Iacobus Belii filius.) was the son and successor of King Beli ap Rhun, and is listed in the royal genealogies of the Harleian genealogies and in Jesus College MS. 20. The only other record of him is the note of his death, which occurred in the same year as the Battle of Chester, with no connection between Iago's death and the famous battle, and with no evidence that Gwynedd had any part in the battle.
He would be succeeded as king by his son, Cadfan ap Iago.
The 1766 publication of Henry Rowlands's" Mona Antiqua Restaurata" says that the archives of the cathedral at Bangor mention Iago as having founded a deanery there('" Iago ap Beli Rex Decanatu Ecclesiam ditavit"').
However, the correctness of the archive's assertion is challenged in Haddan and Stubbs' authoritative" Councils and Ecclesiastical Documents Relating to Great Britain and Ireland", where it is noted that" the earliest historical testimony to a Dean at Bangor is 1162".
In the medieval" Welsh Triads", the death of King Iago ap Beli is described as the result of an axe- blow by one of his own men, a certain Cadafael Wyllt.
In his" Celtic Britain", John
Rhys notes that the" Annals of Tigernach" mention Iago's death and use the word" dormitat"( or" dormitato", meaning" sleep" in the sense of a euphemism for death), contradicting the notion of a violent death.
Further, as the word" dormitato" was generally used in reference to clerics, it is possible that Iago resigned his kingship and thereafter led a clerical life.
