I believed that the 2% Iberian Peninsula may be the reason for my olive skin, and ability to tan at the first sight of sun! But after my update, these are now my results....
Ancestry.com seem to be doing away with 'trace' (low) estimates and this is probably a good idea, because results below 15% were meaningless anyway
This is from ancestry FAQS/information page on 'trace'/below 15%results (my underline)
https://www.ancestry.co.uk/dna/legal/faq#interpret-4Trace Regions are regions where the estimated range includes zero and does not go above 15%, or where the predicted percentage is less than 4.5%. Since there is only a small amount of evidence that you have genetic ethnicity from these regions, it is possible that you may not have genetic ethnicity from them at all. This is not uncommon,
I would have hoped that the results would have given me a time frame of how far they went back...
The below quote is from the same Ancestry FAQS/information page linked above. I'm afraid that, again, the information is all a bit vague.
It maps ethnicity going back multiple generations...targeting your family history a few hundred or even a thousand years ago...
As others have pointed out, the ethnicity part of the results are a waste of time and not to be taken seriously.
'Olive skin' could have come from anywhere in Europe. For example, I have a relative from the North of England whose family are all extremely dark and his ancestors, going back hundreds of years, are
all in local parish records within a small area of rural Yorkshire .
