ヨーカ (スコットランド王)

父の死に伴い、ストラスクライド王に即位した。878年にピクト人の王・ギリック（ヨーカの母方の祖父・ケネス1世の甥）の共同統治者としてスコットランド王位にも就いた。889年にギリックが死ぬと、スコットランド王位を失った。ストラスクライド王位は死ぬまで保持できたとされ、息子のディフンワルに受け継がれた。

• Since the 1990s, academics have accorded Eochaid various names in English secondary sources: Eochaid, and Eochod. Since the 1990s, academics have accorded Eochaid various patronyms in English secondary sources: Eochaid ap Rhun, and Eochaid map Rhun.
• Eochaid is not the only British contemporary known to have possessed a genealogical connection with the Pictish elite. For example, the tenth-century Life of St Cathróe reports that Cathróe was related to both the kings of Alba and Strathclyde.
• The personal name Eochaid is Celtic in origin, based upon an element meaning "horse" (for example, the Old Irish ech is derived from the Proto-Celtic *ekʷos). It was a very common Gaelic name. In Dál Riata, the name may be associated with the Epidii. The name of this population group is derived from Proto-Celtic *Ekʷodii, meaning "horsemen". According to the early mediaeval genealogical tracts Cethri prímchenéla and Míniugud senchasa fher nAlban, the ultimate ancestor of the leading kindreds of Dál Riata was a man named Eochaid.
• Arthgal's death is also reported by the reconstructed Chronicle of Ireland.
• This site — identified in local tradition as "Doomster Hill" — was destroyed in the nineteenth century. The stepped sides of the hill are similar to those of some Scandinavian assembly sites in Britain and Ireland.
