About Ieuaf
Lived 915 – 988 (aged 72–73). Ieuaf was a sovereign.
Ieuaf , perhaps a nickname representing Idwal ap Idwal (died 988) to distinguish him from his father Idwal Foel, was joint king of Gwynedd in northern Wales from 950 to 969 with his brother Iago ab Idwal. He possibly also ruled Powys for some time.
Ieuaf was a son of King Idwal Foel (Idwal the Bald), who had become King of Gwynedd from 916 others that he was executed on his brother's orders.
Ieuaf spent the final decades of his life removed from power, either in captivity or killed shortly after his imprisonment. A recent hypothesis suggests that he fled to the modern-day Peak District (where displaced members of the Idwal dynasty are believed to have sought refuge during periods of internal turmoil), based on later genealogical fragments and Royal family trees with unlabelled members uncovered in hill settlements beyond Gwynedd's eastern frontier. In some cases, individual members or even entire branches of the family tree were apparently removed deliberately, possibly to protect them.
