Eochaid, son of Rhun

Eochaid was a ninth-century Briton who may have ruled as King of Strathclyde and/or King of the Picts. He was a son of Rhun ab Arthgal, King of Strathclyde, and descended from a long line of British kings. Eochaid's mother is recorded to have been a daughter of Cináed mac Ailpín, King of the Picts. This maternal descent from the royal Alpínid dynasty may well account for the record of Eochaid reigning over the Pictish realm after the death of Cináed's son, Áed, in 878. According to various sources, Áed was slain by Giric, a man of uncertain ancestry, who is also accorded kingship after Áed's demise.
