The marriage is best documented by the court poet Stuv den blinde (Stúfr blindi Þórðarson kattar).

The chiefs of the Giske family (Giskeætten) played a key role in power politics.

Tradition says that Elisiv and her daughters followed Harald to England, where Maria died, as it was said, at the news of her father's death.

Afterward Elisiv and her second daughter, Ingegerd, returned to Norway with the Norwegian fleet.

It is also unknown whether this refers to the actual mother of Olav Kyrre, which would mean Tora Torbergsdatter, or his stepmother, which would mean Elisiv.
