Table. Ancestry.com's ethnicity estimate of me, based on a sample I submitted. [Updated 16 Sep 2020]

I gather that this estimate is achieved by comparing the DNA with other customer's submissions and known origins. The most interesting line is the last, which shows some Burmese blood. [Removed in Sep 2020 update.]

It is likely to be less accurate in countries where fewer customers are likely to have submitted samples but we seem to be only about 6% [update: but up to 13%] Asian, in non-technical terms, where 25% of the family was in 'India' at one time. This indicates that only about a quarter of my Anglo grandparents' distant ancestors were native. Inter-marriage in British India was rarer in the C19, but a whole race of Anglo-Indians had by then been created by earlier relationships.

It is slightly surprising that we match so well with the East Midlands of England. [Update: and Scotland and Ireland and Sweden but all of these have a low minimum. The upper range for England is less than half though.] 

The Scandinavian and Balkan blood is inexplicable - perhaps from Normans in Jersey, or part of the mix in British India ('Anglo-Indian' meant anyone with a European father and an Asian mother). [Update: Norway and Balkan blood not reported in Sep 2020 update, but Sweden is still there. Northern India has made a comeback - I wonder if N India was mis-identified as Roma?]

[Update: one makeup within range, closer matching known pedigree would be 48% England, 7% Scotland, 9% Wales, 13% India

In an earlier test, my female maternal cousin's mitochondrial DNA was identified as of an unusual 'fertile crescent' Middle Eastern origin.
