Sæferð: King of the Sycgan, some debate that he is the Sigeferþ of Beowulf and Holthausen translates the name Seefried. We cannot be certain of his identity.
Sycgan: Only otherwise known from the Finnsburug Fragment, l24, where they are the Secgena(gpn).
Sweon: The Swedes of Uppland (tgn, 7009866, http://vocab.getty.edu/page/tgn/7009866)
Ongendþeow: A king of the Swedes mentioned in Beowulf (as Ongenþoew), his name becongs Angantyr in Old Norse. The Ongend- element means sting or prick and Malone then extrapolates to 'phallus', associating Ongend- with a priest of a fertility cult, perhaps Yngvi Freyr.
