U 11 is the Rundata designation for a runestone that is located near the ruins of the old king's dwelling at Alsnö hus near HovgÃÂ¥rden on the island of Adelsö in Sweden.
Tolir is described as being a "bryte," which is an old Norse word for a thrall who worked as the thralls' foreman. The word "bryte" comes from "to break," in the meaning of breaking bread, so "bryte" can be interpreted as the person who serves out food.
Gylla was Tolir's wife. Since the text mentions a kunungi or kunungr, Old Norse for "king," HÃÂ¥kon is believed to be the reigning king HÃÂ¥kan the Red, who is generally accepted as ruling during the 1070s.
