The inscription says that it is raised in memory of Haraldr, the brother of Ingvar, and he is believed to have died in the region of the Caspian Sea. A subject that has been vividly discussed is why the runestone is raised only after Haraldr and not after Ingvar, and the most widely accepted explanation is that Tóla was only Harald's mother and that the two men were only half-brothers. It is also possible that there were originally two stones of which one was in memory of Ingvar, but that Ingvar's stone has disappeared. A third possibility is that "brother" refers to brother-in-arms, blood brother, or something similar, and this is a use of the word that appears on one of the runestones in Hällestad in Scania.
