Commercial ancestral DNA testing reveals the Genetic Diversity of Ireland

The power of commercial ancestral DNA testing continues to amaze me.

Criteria for the Surnames of Ireland database

In the course of this website I have had some emails from those involved in surname groups questioning the accuracy of some maps. I have used 2 sources in making these maps: (1) 1911 census of Ireland (2) MacLysaghts book: 'The Surnames of Ireland.' As a scientist I am trained to look for, or spot paterns emerging in the results. With surnames that pattern can reflect ethnicity. For example Irish Surnames (lets say those of Gaelic Irish origin) typically begin with O' or Mac, people with these 'Irish Surnames' are also typically over 90% Catholic in 1911.

New 'Hickey' Case Study Added

I always ask my customers to allow me to publish online their Case Studies, and thank you to Mr Hickey for allowing me to do this. The objective is 2 fold; Firstly everyone's DNA story is different and the more examples that can be put on the website the more people can understand the process and apply this technique to their own DNA results. Secondly I hope it will encourage more people to take the DNA tests, as at the end of the day the findings from each of these Case Studies can be confirmed through DNA testing.
