Eurogenes K36 Similarity for Irish regions

[Sikeliot]

I am comparing them to England, Northern Germany, and Denmark to gauge British, continental Germanic, and Viking influences. I have come up with the "average" similarity to each and provided ranges.

Differences were small but overall:

- Clare is the least similar overall to England, Denmark, and Germany. It is the only region that has never had Viking settlements, had no plantations, and remained outside of Norman control.
- The rest of Western Ireland (Connacht, Cork/Kerry/Limerick) are slightly more Scandinavian than eastern Ireland.
- Eastern Ireland (Leinster) and Northern Ireland (Ulster) are, unsurprisingly, closest to England and received the most English settlers.

Clare: N=8
England: 85 (range 79-90)
Denmark: 81 (range 75-85)
Germany: 79 (range 72-87)

Galway, Mayo, and Roscommon: N = 9
England: 86 (range 84-89)
Denmark: 83 (range 79-87)
Germany: 79 (range 79-83)

Cork, Kerry, and Limerick: N = 11
England: 87 (range 84-91)
Denmark: 83 (range 81-90)
Germany: 82 (range 77-87)

Eastern Ireland (Wicklow, Laois, Waterford, Westmeath: N = 6
England: 88 (range 86-92)
Denmark: 82 (range 80-86)
Germany: 80 (range 78-83)

Northern Ireland: N = 2
England: 88 (range 86-89)
Denmark: 83 (range 81-84)
Germany 81 (range 80-81)


I can post the individual images of the similarity maps if that helps.

Do people only seem to care when I post about Southern Europe? This was interesting and I spent a lot of time on it.

Doesn't make sense for the west to be more Scandinavian than eastern Ireland. Of course Limerick was a Viking settle but still Dublin was a large Viking settlement and also eastern Ireland always had more English, Norman settlement. Wexford is the area that had a lot of both Viking and Anglo-Saxon input. Not sure how accurate looking at k36 is? I would be more inclined to make conclusions from history and also studies like the Irish DNA Atlas and Insular Celtic papers. Although I'm always interested in your input on Irish genetics Sikeliot. I do think Gedmatch is good and some of the calcs on there are good for looking at population similarities and distance etc but I don't think things like admixture can be deduced too accurate from Gedmatch. Gedmatch is basically just mathematical and placing you in a best population fit so you can get some odd things like 93% Irish and 7% Aluet etc.

The greater number of Scandinavians may have gone to eastern Ireland, but if the west had a much lower population density (which I believe it did), fewer Scandinavians there could have a larger impact on the DNA.

Insular Celtic paper did suggest, both through measuring an Anglo-Saxon component in Ireland and through PCA that Leinster (and especially Wexford) as well as Northern Ireland had an elevated amount of this.

I suspect with good sampling, everything from Dublin down to Waterford, including places like Kilkenny, Wicklow, etc. would have a higher amount of English.

but it is worth noting all Irish from all regions are close to the English, Welsh, etc.
