| 23&Me Ancestry Composition. 25 June 2026. |
23&Me is rolling out updated Country Match information in its Ancestry Composition report (for comparison, here's the earlier version). There are some fascinating additions in the country reports, showing specific regions in England and Ireland where my matches report ancestors. Greater London isn't a surprise, but it's cool to see how this granularity compares with the AncestryDNA regions update from last October. It's also cool to see 23&Me focusing on Longford & Roscommon in North Central Ireland.

It's very interesting to see 23&Me focus in on Abruzzo and Calabria for my 3.1% Southern Italian.
