His name means "Bear-slayer", because as a young man, living as the adopted son of the Lord of Lielvārde, he kills a bear by ripping its jaws apart with his hands.
Hans navn betyder "bjørneflænser", for som en ung mand, der levede som adopteret søn af Herren af Lielvārde, dræbte han en bjørn ved at flænse dens kæber fra hinanden med hænderne.
