Angantyr
Angantyr is also the Swedish name of Ongentheow.
Angantyr was the name of three male characters from the same line in Norse mythology, and who appear in Hervarar saga, Gesta Danorum, and Faroese ballads.
The last generation named Angantyr also appears to be mentioned as Incgentheow in Widsith, line 115, together with his father Heiðrekr (Heathoric), half-brother Hlöð (Hlith) and Hlöð's mother Sifka (Sifeca).
