Please see Darrell Wolcott: The Royal Family of Powys - The "Mael Maelienydd" in Medieval Pedigrees; http://www.ancientwalesstudies.org/id76.html. "If Clydog had any sons at all, they were yet toddlers when he was killed. A Brut entry for 938 says that Hyfaidd ap Clydog died; either he was a young man who contracted an illness or the son of a different Clydog. The same entry says Meurig also died that year, with the Red Book of Hergest version making him a brother of Hyfaidd. Neither the notice in Annales Cambriae nor the Peniarth Ms 20 version of the Brut make the men brothers, but do make it clear both "died" as opposed to having been slain. We remain unconvinced either man was definitely a son of Clydog ap Cadell. Often the Brut, when it records men who died prematurely, heaps praise on them and laments their early passing. Men simply noted as having died usually lived out a full life and there was nothing unremarkable about such a death. In any event, no son of Clydog ap Cadell named Cadfael occurs until the 16th century when he is used to link "Mael Maelienydd" to the clan of Rhodri Mawr. " (Steven Ferry, October 21, 2019.)
