Beli ap Rhun
Beli ap Rhun( c. 517 – c. 599) was King of Gwynedd( reigned c. 586 – c. 599).
Nothing is known of the person, and his name is known only from Welsh genealogies, which confirm that he had at least two sons.
He succeeded his father Rhun ap Maelgwn as king, and was in turn succeeded by his son Iago.
Beli was the either the father or grandfather of Saint Edeyrn.
The royal genealogies of the Harleian genealogies, Jesus College MS. 20, and" Hengwrt MS. 202" show him as the ancestor and descendant of kings, and thus presumably a king himself.
The" Bonedd y Saint" says that he is the ancestor of Saint Edeyrn( the" Bonedd y Saint" says that he was the son of Nudd or Lludd who was the son of Beli, while" Hengwrt MS. 202" says that he was the son of Beli).
One of the medieval" Welsh Triads" mentions a certain' Rhun ap Beli', implying that there was yet another son of Beli, who was famed for his military exploits.
The name is repeated elsewhere in medieval poetry, such as in Hywel Foel's( fl. c. 1240 – 1300)" awdl" lamenting the capture and imprisonment of Owain ap Gruffudd, where he likens Owain to Rhun:" Who if free, like Rhun the son of Beli, Would not let Lloegria burn his borders".
There is no confirming evidence that such a person existed, and it is contradicted by records such as the royal genealogies.
Scholars such as Thomas Stephens have concluded that this is a mistake, and that the intended person was someone else.

Eiludd Powys
Eiludd Powys was an early 7th-century King of Powys.
One theory asserts that when Manwgan ap Selyf came to the throne in 613 he was a young boy, which led to an invasion of Powys by Eluadd ap Glast
(alias Eiludd Powys), the erstwhile King of Dogfeiling.
The usurper probably managed to hold the throne for some thirty years or more before he was killed fighting the Northumbrians, possibly at the Battle of Maes Cogwy (Oswestry) in 642.
The Dogfeiling dynasty was finally crushed by the Saxons around 656.
He was more likely the son or younger brother of Selyf "Sarffgadau" ap Cynan Garwyn.
It is not known which he is as there are two accounts one in the Jesus College Ms.20
that makes him the son of Selyf and brother of Manwgan whereas the Harleian Ms. 3859 makes him the brother of Selyf Sarffgadau, he could be either as it is not unheard of that a brother succeeds in absence of a mature heir (see Rhyddfedd Frych), as well as the eldest being overlooked as successor by their father
(see Gruffydd ap Llywelyn Fawr and Dafydd ap Llywelyn).
But what is interesting is a reference to the descendants of Selyf, serpents of Battle by the Powysian Court Poet Cynddelw Brydydd Mawr and that he specifically during this time of the 12th Century worked for the Powysian Royal family and then after their fall, went to work under Gwynedd and then later Powys Wenwynwyn.

Abd al-Muttalib
Abd al- Muttalib Shaybah ibn Hashim( c. 497 – 578) was the grandfather of Islamic prophet Muhammad.
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.
Gwylog ap Beli
Gwylog ap Beli was one of the rulers of the Kingdom of Powys during the late 7th to early 8th Century, son of Beli ap Eiludd.
There is also a small possibility his mother was Heledd ferch Cyndrwyn the narrator of the Canu Heledd, being that she would have been welcomed by his father Beli after the defeat at Maes Cogwy.
