Question: What is the place of birth of Eiludd Powys's father?

Knowledge 1: 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.20that 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. [SEP] Knowledge 2: Cynan Garwyn
Cynan Garwyn was king of Powys in the north-east and east of Wales, who flourished in the second half of the 6th century.Little reliable information exists which can be used to reconstruct the background and career of the historical figure.Available materials include early Welsh poetry, genealogies and hagiography, which are often late and of uncertain value.
