The "Annales Cambriae" note s.a. CCX+6 (c. 760) Dunnagual filius Teudubr, who may be the son of Taudar mac Bile of the "Annals of Tigernach". The "Annales Cambriae" does not specify his status, but he may plausibly have been king at Alclut. The following three individuals in the Harleian genealogy, Eugein, Riderch and Dumnagual, are unattested elsewhere. These are repetitions of three of the most famous names in the canon, and it must be suspected that they were supplied to fill a gap in the genealogical record. The insertion of Rotri between Dumnagual and Teudubr is a modern error based on a misinterpretation of "Annales Cambriae": s.a. CCX (754) Rotri, rex Brittonum, moritur. This Rhodri is almost certainly Rhodri Molwynog ("bald and grey") m. Idwal Iwrch, a prince of Gwynedd.
