Også mange amatør-eksperter arbejder. Her er en oversigt over de mange data. De tre største Y-haplogrupper fundet i 276 hovedsageligt "gamle vikinger" er I1 32%, R1b 29% og R1a 21%.On Gotland, there are much more Danish-like, British-like and Finnish-like genetic components than Swedish-like components, supporting the notion that the island may have been marked by extensive maritime contacts during the Viking-Age. On Öland in Sweden, we observe high genetic diversity and the most variable patterns of recent ancestry in Scandinavia.
In conclusion, the results for Gotland and Öland agree with the archaeological record, suggesting that Öland and Gotland were important trading posts from the Roman period onwards.
Our findings do not agree with the view of an overall highly connected population in Viking Scandinavia. Rather, we find clear genetic population structure within Scandinavia.
Our fine-scale ancestry analysis based on genomic data largely support the Viking expansion patterns inferred from archaeology. The eastward movements mainly involved individuals with Swedish-like ancestry, while the Viking individuals with Norwegian-like ancestry travelled to Iceland, Greenland, Ireland and the Isle of Man. A Danish-like ancestry component is more pronounced in present-day England, which is also in accordance with historical records and still visible in place-names, and modern genetics. Importantly, however, it is currently impossible for us to distinguish Danish-like ancestry in the British Isles from that of the Angles and Saxons, who migrated in the 5th-to-6thcenturies CE from Jutland and Northern Germany.

Nej men, jag tror inte det här egentligen är något väldigt konstigt. Ställen som Öland och Gotland måste ha varit bra ställen för handel, och med något begränsade områden kan där också ha funnits härskare som tog makten utan någon traditionell rätt.
