According to Lady of the Labyrinth (a Norwegian scholar):
... many of the German tribes had legends of a Scandinavian homeland, and many tribes did in fact separate in two groups during the Migration Age (beginning in the second century BC and lasting until the fifth AD), where the second group emigrated to the southeast – which is why Poland was so densely occupied by Germanic tribes. Thus it is entirely possible that we see a Scandinavian and a continental branch of the same original tribe, like we do with the Swedish Götar (Geats, Gauts) and the Central European Goths.
In 1883, Grimsby (“Nordisk Familjebok”) suggested that the Hilleviones were an early population of Halland in Sweden. If so, they could be the same as the Hallin tribe of the Scandza island, mentioned by Jordanes in 551 AD. Jordanes place the Hallin in Scandinavia. After having described the Andogit and Scredefennae of Northern Norway, he mentions one tribe of Suehi (possibly the Swedish tribe known as Svear) before he counts up several other tribes, among them the Hallin:
According to Tacitus, the Helveconae are one of the tribes belonging to a confederation of tribes known together as the Lugii, (there will be a later post on the Lugii). About the Helveconae is simply said to be among the most powerful Lugii tribes. His geographical description is usually thought to be referring to areas in Poland, although it could easily be understood as Norway or Sweden.[/quote]
[quote]The Goths and the Vandals (if indeed they are distinct) both are assumed to have come from Sweden. Many believe, without much evidence, that there is a connection to the Hilleviones of Sweden. The name can probably be segmented Helvec-on-ae, where the -on- is a Latin productive suffix used to generate people and place names. Helvec- might be further segmented as Hel-vec-, where -vec- might be “settlement”, as -ing would be “people.” As for the Hel-, there are as many possibilities ...
Hail my patroness Hel!
Note in the map of Halland, there is a subarea within Halland called Hylte (which links to my feeling that the name was associated with the name Hoyt for some reason.
