Ulf Uspakson stood in great esteem with King Harald; for he was a man
of great understanding, clever in conversation, active and brave, and
withal true and sincere. King Harald made Ulf his marshal, and married
him to Jorun, Thorberg's daughter, a sister of Harald's wife, Thora. Ulf
and Jorun's children were Joan the Strong of Rasvol, and Brigida, mother
of Sauda-Ulf, who was father of Peter Byrdar-Svein, father of Ulf
Fly and Sigrid. Joan the Strong's son was Erlend Himalde, father of
Archbishop Eystein and his brothers. King Harald gave Ulf the marshal
the rights of a lenderman and a fief of twelve marks income, besides a
half-district in the Throndhjem land. Of this Stein Herdison speaks in
his song about Ulf.
