“germans”, “french”, “danes” weren’t a thing. up until recently. they are genetically diverse groups.
I was under the impression that the DNA kits described actual ethnic groups and showed a map of the distribution of those groups overlaid on modern political borders or region names. Here’s the page on 23 and Me’s reports, which have a lot more granular detail, mapped onto modern political borders for reference, but where any listed nation or territory may have up to dozens of different sub-groups listed.
