Pretty much (if by half you mean circa 5%). And Dutch of course. Fur shure.
But not French.
This is kinda true. Never have I seen such a bang average bunch of no marks (in terms of recorded history*) almost exclusively from round these parts. We borrowed the odd gene here and there from exotic far afield locations like east leake and swanwick, but in the main you could throw a blanket over where my ancestors located themselves. The mix suggests we were here when the Vikings popped round for a fuck, but we never gave it up for the French.
* The family tradition of 'rather die than go to Australia' has some historical precedence. The one family member in recorded history that troubled the scorers, did so for being transported for stealing a sheep. Taken sick on the journey, died on arrival, so no Aussie relatives.
Is a tough price to pay, but good lad for doing the right thing.
