@CapriCaput@ulfcytel I recently took a Big Y-700 and expect my results soon. I know I'm under L47 from prior testing, so I'll get back to you as soon as my results come in to see if we share R-FT193543. My direct paternal line traces back to the city of York in the mid 1500s with the surname Myles.
@CapriCaput@ulfcytel However, because S9257 formed around 1400 BCE, it's too old on its own to prove where your family lived in recent history. If you wanna know more, I'd suggest upgrading or taking a Big Y-700 test from FamilyTreeDNA and finding out your terminal SNP.
@CapriCaput@ulfcytel From what I know, a 10th-century Viking was found carrying S9257 at Hofstaðir, Iceland. If your specific paternal ancestry is Northern English, your paternal roots are most likely from the tribe of the Angles or from a later Viking settler of Jorvik/Danelaw.
For the most part it was larping as a racial elite to hide the reality that the people are by and large Picts and Gaels who had lost their identity in the ensuing Anglicization of the Northeast.
If the average person in the northeast traced their ancestry back to the 1400's, they might be in for some surprises. Your "English" names suddenly transform into Gaelic. Norse influence outside of Shetland and Orkney, was greater among the regions which are still Gaelic today than they ever were in the northeast.
There was some migration into the region which helped that along, establishing English as the commercial language in the towns, but the overall genetics of the northeast did not shift radically from the early medieval.
