How much Germanic/Insular Keltic do Iceland have?

[Jingle Bell]

I know that a good part of their MtDNA is of Insular C. Origin, but what abt Autossonomical which is what rly matters? Someone have any model in g25 or qpAdm? Or just a article with a good base?

"Genetic studies in Iceland reveal about 19% of the males and 62% of the females have Irish/British Isles DNA. Males are 80% and women are 37% Norwegian.
There are many names of people and places in Iceland that derive from our Irish ancestry."

They look strongly Nordic imo, far closer to the Norwegians than to the Irish.

Wait, but the study is talking abt YDna/mtDna correct?

Originally it was a 50/50 mix of Gael vs Scandinavian but now it is 30% Gael vs 70% Scandinavian. This is on autosomal dna. Iceland is my 2nd closest country on G25 after Ireland.

This is the study that goes into detail about this. This is only an extract but the full study could be possibly available online. It used to be.

Also there was another dna study looking at some of the ancient genomes from Iceland and the Insular Celtic genomes were mostly similar to people from Donegal, the Hebrides and Argyll. There was also genomes that share more affinity with Munster.


We first confirmed that our underlying modern British and Irish structure does not dramatically change the ancestry estimates of the ancient Icelanders (SI Appendix, Supplementary Data 7). Using Human Genome Diversity Project (HGDP) Yorubans as an outgroup, we calculated the D statistic of 2 groups of ancient individuals to either British or Irish genetic regions, or modern Scandinavia (Fig. 4). The British or Irish regions included some merged fineSTRUCTURE clusters in Orkney, Shetland, and the Hebrides, Donegal (Donegal 1 and 2), Ireland (N Ireland, C Ireland), and S Ireland (Munster) to increase sample sizes of those regions. The 2 groups of ancient Icelanders were those of predominantly Gaelic (n = 7) or Norse (n = 10) ancestry (see SI Appendix, Supplementary Data 7 for more information). All but one of the predominantly Norse ancient Icelanders share significantly (Z > 3) more drift with modern Scandinavian individuals than with the British sample (Fig. 4). The predominantly Gaelic ancient Icelanders show differing affinities across the British and Irish groups. They show the greatest affinity to the “Gaelic” populations of Scotland and Ireland as opposed to English regions (Fig. 4). The smallest estimates of D, which correspond to the largest British/Irish affinity compared to Scandinavia, are to Donegal, the Hebrides, and Argyll. This corresponds to the northwestern region of the British Isles and Ireland which is known to have experienced heavy Viking activity (1). Interestingly we observe some ancient Gaelic Icelanders, in contrast, share affinity with different clusters (SI Appendix, Fig. S8), notably KNS-A1, who shows greater affinity to the south of Ireland. Our results provide genetic evidence either of Viking-mediated migration of Gaels from the northwest of the British Isles and Ireland or, at least, that these modern regions represent the best proxy of the true ancient Gaelic source populations in the absence of direct ancient DNA sampling.
