From the U - Version of Hervor' s Saga we learn much about Starkad' s ancestors. " There was a man Arn Grim . He was a Giant, and a rock dweller. He took Ama, Ymir's daughter from Ymisland, and made her his wife. Their son was Hergrim, who was called Half - Troll. He was sometimes with mountain Giants, and sometimes with men. He had the strength of a Giant. He was all- knowing in the ancient arts and a great warrior. He went to Jotunheim and took Ogn Elf - Burst home with him, and made her his wife. Their son was called Grim. Before this she had been promised to the warrior Starkad Ala - Warrior.
Now this man, Starkad Ala - Warrior, lived by the Alufoss, ( Alu waterfall ). He was descended from that race of Giants called Thurses, and was like them in many ways, and he had eight arms. Storkvid was the name of his father. Ogn Elf - Burst was Starkad' s betrothed, and a man named Hergrim took her from him while Starkad was away, having gone north over the Elia creeks, but when he came back he challenged Hergrim to a duel on an island, to fight for the woman. They fought by Efsta Foss ( Falls ), at Eid. Starkad had 8 arms and wielded four swords at once. He had the victory there, and Hergrim fell. Ogn, who was watching the battle and saw Hergrim fall fell on her sword and ended her life. For she did not want to marry Starkad. Starkad seized all the wealth that Hergrim had amassed, and took his son Grim as well. Grim grew up with Starkad and grew both bigger and stronger than most men.
Alf the King of Alfheim had a daughter named Alfhild. One autumn day a great disablot, or sacrifice to the Goddesses, was made by King Alf. Alfhild accompanied her father to the sacrifices. She was the fairest of all women as were most of the people from Alfheim. That night as she bloodied the altar in sacrifice Starkad Ala - Warrior took Alfhild away and took he back to his home. King Alf called on Almighty Thor to aid him and bring his daughter back. Thor agreed and killed Starkad Ala - Warrior, and allowed Alfhild to go back to her father. Hergrim' s son Grim went raiding when he was just 12 years old . He became a great warrior and married Bauggerd, the daughter of Alfhild and Starkad Ala - Warrior . Grim lived on the island of Bolm in Halogaland. Their son was Arngrim Berserk, who lived on Bolm and was a fierce warrior.
I do find it ironic that Grim, the son of Hergrim, who was killed by Starkad Ala - Warrior, winds up marrying Bauggerd, the daughter of Starkad Ala - Warrior and Alfhild. But then again the Sagas and Eddas are full of irony and surprises. Next time the story of Starkad the younger ( Storvirkrsson ), from Gautrek's Saga.
Go with Odin' s wisdom, Freyja's love and Thor's protection !
