Note 374 — Chapter VI · THE KINGDOM OF SCONE.

See Chron. Picts and Scots, p. 136. Tighernac has at 713, ‘Cinaedh mac Derili et filius Mathgernan jugulati sunt. Tolarg mac Drostan ligatus apud fratrem suum Nechtan regem.’ As Nechtan was son of Derili, he could not have been brother of Tolarg, son of Drostan, and the expression ‘fratrem suum’ must refer to Cinaedh, who was also son of Derili, and was probably slain by Tolarg. Again, in 734 the Ulster Annals have, ‘Talorggan filius Drostan comprehensus alligatus juxta aciem Ollaigh;’ and in 739 Tighernac has ‘Tolarcan mac Drostan rex Athfhotla a bathadh la h’Aengus’ (drowned by Angus). The process of change in the name is first Athfhotla—then Atheodle—then Atholl.
