Rǫgnvaldr Eysteinsson

Rognvald Eysteinsson was the founding Jarl of Møre in Norway, and a close relative and ally of Harald Fairhair, the earliest known King of Norway. In the Norse language he is known as Rǫgnvaldr Eysteinsson (Mǿrajarl) and in modern Norwegian as Ragnvald Mørejarl. He is sometimes referred to with bynames that may be translated into modern English as "Rognvald the Wise" or "Rognvald the Powerful".
