How many can actually trace that far back though?
Statistics mean we don’t need to. 1000 years, assuming most generations spaced 20 years apart and no in-breeding, would give you 1,125,899,906,842,624 unique ancestors the last time the Vikings invaded. In the doomsday book it’s estimated there are less than 2million people in England eight decades later. Which obviously means;
a) we’re all quite a bit inbred
b) we’re probably all related to you and your norse king.
My surname at least goes back to Feudal times in the North West which is still where most of my family live, although I’ve bumped into one other with the same name who’s family tree involved emigrating to Russia from there several hundred years ago so we clearly got about a bit. And my dad’s side all have big noses and afro’s (proper 70’s microphone afro’s) so clearly someone was playing away from home down at Lancaster docks.
