Well, I think that may have been somewhat resolved by the Normans so greatly depleting the incumbent population who were there nigh on a millennium ago. Normans got rid of many of the people who were victims of their Norse relatives by going up and simply reducing that population with their ‘Harrying of the North’.
Also, this grievance issue may extend to Iceland now. They reckon many of the female ‘settlers’ were of Irish and Scottish stock. Not voluntarily, I’d suspect. To the extend that even today the majority of the maternal DNA is still of that origin. Irish and Scottish ancestry carried on the male line is only about 20%. Now some may have been because of intermarriage, but we do know they had thralls.
They also traded, it must be said. Whether or not it was on the proceeds of acquisitions from these sort of shopping centres called Monasteries, I don’t know.
In turn, so back estuarine towns and cities in Ireland were established and settled by the Vikings. All the better to carry out raids. Dublin, Wicklow, Arklow, Wexford, Waterford, Cork, Limerick. Strangford and Carlingford Loughs in NI were also Viking bases.
Reckon they’ll still say ‘you don’t need to thank us’.
