Ancestry's Ethnicity Update Is Finally Here - Share Yours!

[Gadget]

Are you saying Ancestry narrowed down Cornish ethnicity to a distinct part of the county? And could this have been because it was using other trees that already had the 2x great grandmother born in a specific location?

Scroll down to Devon and Cornwall and you find these regions:

Devon
East Cornwall
Kerrier, Cornwall
West Cornwall & the Isles of Scilly

So I assume emeraldcity means one of these regions.

Devon
East Cornwall
Kerrier, Cornwall
West Cornwall & the Isles of Scilly

They don't define these regions. What does East, West and Kerrier mean?

"They don't define these regions ..."

Good grief, the whole thing is only about 115 km long [measured on the diagonal].  That's around half the size of Long Island, NY.

There must be one of their maps somewhere.

Precisely. And Kerrier, in particular, is a small area whose boundaries have changed over the centuries. The most recent incarnation stretched to the north coast; previous incarnations didn't do this. How can Ancestry get so granular, and on what basis?

Our ancestry is Cornish back through many generations (based on DNA and paper research) and yet Ancestry can't pinpoint our ethnicity precisely, even though it seems to be able to do this for someone with just one 2x great grandmother born in the county.

I'd like to see this. Can't find it myself.

Visualise a map of Cornwall.

Kerrier is the part to the west of the middle
West of that is West Cornwall
East of that is East Cornwall

Note - I used to live in Plymouth once upon a time

Thanks, Gadget, very familiar with Cornwall having lived there for many years, and Kerrier, East and West are meaningless definitions. What does Ancestry actually mean by these terms?

[Gadget]

Your guess is as good as mine. Maybe emeraldcity could tell us.
