Please see Darrell Wolcott: Rethinking the Gwent Pedigrees; http://www.ancientwalesstudies.org/id24.html. In this paper Wolcott shares Bartrum's view that the father of Tewdrig was Llywarch ap Ninniaw. In a subsequent paper, The Father of Tewdrig of Gwent; http://www.ancientwalesstudies.org/id27.html, Wolcott expresses doubt as to the parentage of Tewdrig. It could be either Llywarch or Teithfallt as stated in earlier manuscripts. In a third paper, Another Look at Teithfallt of Gwent; http://www.ancientwalesstudies.org/id27.html, Wolcott offers a history with a conjecture as to how the father of Tewdrig could actually have been Theithfallt ap Ynyr (Honorius.)

Please see Darrell Wolcott: Another Look at Teithfallt of Gwent; http://www.ancientwalesstudies.org/id168.html. In this later paper Wolcott returns to the older works that show the father of Tewdrig to be Teithfallt ap Ynyr Gwent (Honorius.) He adds that Llywarch ap Ninniau should be listed as d.s.p. (Steven Ferry, February 25, 2020.)
