The impact of researching DNA on the One-Name Study is yet to be ascertained. The “kits” were sent off in 2018 and, as yet, there is little in the area of results. But these are early days.

As of January 2019, it was estimated that some 26 million people had been tested with Ancestry of Lehi, Utah USA and 23andMe of Mountain View, California USA being the main testers. Most of those tested are from the USA. Other companies have large data collections – but these can include data from other testers. For example MyHeritage (Israel) is seen as the 3rd largest with nearly 3 million profiles and FamilyTreeDNA (Houston USA) over 2 million.

Ethnicity Estimates

Estimates of Ethnicity are gained by the company comparing the DNA sample with a “reference group” whose heredity has been rigorously determined through documentation. As the numbers of people tested increases, the reference group is updated – which explains how the estimates can change over time.

FamilyTree DNA

Using the Autosomal DNA, the “Origins 2” tool shows 75% British Isles, 24% West and Central Europe with <1% Asia Minor.


The estimate is 79% England, Wales & Northwestern Europe; 14% Ireland and Scotland with 7% Norway. For England & Wales – there were concentrations in Devon and “North Yorkshire, East Riding and Lincolnshire”.
