Deep Ancestry is our broadest report — it covers 130+ ethnicities, sub-regions, and 1,800 communities, including the British Isles. But the British Isles is a region where many of our users have strong family roots, and we have access to richer datasets there. That let us build a standalone algorithm specifically for British and Irish heritage.
The other big difference: Deep Ancestry doesn't include ancient DNA matching, and this report does. So in short, you get a more detailed regional breakdown of British and Irish roots, plus the most detailed ancient DNA matching we offer for these regions.
