Ragnall mac Somairle

Ragnall mac Somairle (also known in Gaelic as Raghnall, Raonall, Raonull; in English as Ranald; in Latin as Reginaldus; and in Old Norse as Rögnvaldr, Røgnvaldr, Rǫgnvaldr; died 1191/1192 – 1210/1227) was a significant late-twelfth-century magnate, seated on the western seaboard of Scotland. He was probably a younger son of Somairle mac Gilla Brigte, Lord of Argyll and his wife, Ragnhildr, daughter of Óláfr Guðrøðarson, King of the Isles. The twelfth-century Kingdom of the Isles, ruled by Ragnall's father and maternal grandfather, existed within a hybrid Norse-Gaelic milieu, which bordered an ever-strengthening and consolidating Kingdom of Scots.
