Eochaid ab Rhun
Eochaid ab Rhun (fl. 853–889) was the son of Rhun, British king of Strathclyde, by a daughter of Cináed mac Ailpín, king of the Picts. After Áed mac Cináeda was killed by Giric in 878, sources link Eochaid with rule over the Picts, perhaps reigning alongside Giric while he retained Strathclyde.
In 889 Eochaid and Giric were driven out; their successor, the Alpínid Domnall mac Custantín, may have been responsible. Nothing more is recorded of Eochaid.
