November-December issue of British Archaeology: The ancient British genome: writing new histories

The article begins on page 14. Most Barnes & Noble bookstores in USA carry the magazine. The article is not available online at this time.

The article reviews four studies with DNA results from 23 people: 4 Iron Age; 11 Roman and 8 Anglo Saxon - 12 men and 11 women. There are a number of charts in the article and details of each individual on pages 24-25.

Here are citations to three studies discussed in the British Archaeology article I posted about last nigh​t​ as well as citation​s​ to ​two other aDNA article​s​ mentioned but not discussed:

The conclusion is that there is genetic continuity through the Roman period with two African and one Middle Eastern individuals as exceptions, and then a genetic change in the Anglo-Saxon era from ~400-900 A.D. 20% to 40% of modern British ancestry can be attributed to the Anglo-Saxons.

Any error in interpretation is mine.
