Another gem from St. Magnus – Earl of Orkney by John Mooney.. This chart shows the family connection between Malcolm II, King of Scotland and the Earls of Orkney, including Magnus Earlandson. As it turns it, Malcolm’s bloodline also connects the Earls of Orkney to King Magnus Barelegs of Norway, and Henry I of England.
When Sigurd II died at the Battle of Clontarf, Malcolm II raised young Thorfinn at the Scottish royal court, and later granted him the title of “Mormaer of Caithness”. Because of this bond, Caithness was largely under the control of the Orkney Earls until the treaty of Perth.
