List of Famous people named Ragnall

Ragnall mac Somairle 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.

Ragnall mac Gofraid was King of the Isles and likely a member of the Uí Ímair kindred. He was a son of Gofraid mac Arailt, King of the Isles. Ragnall and Gofraid flourished at a time when the Kingdom of the Isles seems to have suffered from Orcadian encroachment at the hands of Sigurðr Hlǫðvisson, Earl of Orkney. Gofraid died in 989. Although Ragnall is accorded the kingship upon his own death in 1004 or 1005, the succession after his father's death is uncertain.
