According to a much later tradition, dated to turn of the twentieth century and perhaps as early as the late eighteenth century, the grandfather of Somairle mac Gilla Brigte, King of the Isles (died 1164), Gilla Adamnáin, had a daughter who married a Norwegian king—a king who seemingly corresponds to Haraldr gilli himself.
Although there is no way to confirm the claim itself, such a union is not implausible, and may correspond to the relationship between Bjaðǫk and Haraldr gilli.
Certainly, Somairle himself had a daughter named Bethóc.
Nevertheless, the notion of an affiliation with Somairle's family postdates the printing of Heimskringla, which could suggest that this source spawned ideas of a familial connection.
