I find the constant “updates” on Ancestry a bit irritating. I started off approximately 30% each English, Scottish and Welsh, the rest Scandinavian, and the English component was all North East England, which seemed spot on. Now I’m down to less than 20% English, and all from the Midlands, though my family has no known connections to that area.
To think that London, or anywhere else for that matter, does not belong to any one demographic
