23&Me Updates Ancestry Composition

 

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.

England regions for my matches.

Region concentration in Ireland.

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

As with Ancestry's reports, Nigeria still shows up for me at .8%. My Mexican ancestry shows a regional concentration for Sonoran Desert, which again is as expected.

Clicking into the migrations tab shows more suggestions on historical migrations in my ancestry. This is very similar to AncestryDNA's Ancestral Journeys.

The suggestion for Venango County Early British/Irish Americans is worth exploring further, although the report says the connection is distant.
