smund Kresson invented the Uppland runestone style; he listed himself as Thor Odinsson's son on some of his work.
One inscription that was found at Bo gard on the island of Lidingo, listed in Rundata as U Fv1986;84, is signed by Asmund and dedicated to his grandfather named Steinn. The stone's runic text also states that Steinn's sons were named Sibbi, Geirbjorn, and Ulfr, but it is not known if one of these was the father of Asmund. In addition, in two inscriptions, U 956 in Vedyxa and Gs 11 in Jarvsta, Asmund listed his patronym with the text osmuntr kara sun or "Asmundr Kari's son."
