The first earl of Møre was Rognvald Eysteinsson, a close friend and ally of King Harald I of Norway.
He is called by the byname Rognvald Mørejarl (Rǫgnvaldr Mœrajarl) in the Heimskringla and Orkneyinga saga.
[1] During the early Viking Age, Norway consisted of a number of petty kingdoms.
Subsequently, King Harald I granted land to his sons and other earls who swore fealty to him.
The first sitting earl of Orkney was Sigurd Eysteinsson, brother of Rognvald Mørejarl.
