A detailed report on progress with the study so far, including the detailed findings by family name can be accessed on this page.

As of August 2018, key headline findings from the study so far are:-

The ancestral Y-DNA signatures of over 100 (out of 130 in total) Manx male genetic families have been fully identified. Another 18 families have been partially classified. 
The Y-DNA results of more than 500 men of Manx origin are included in the study database.
In the period immediately after the Scandinavian occupation of the Isle of Man (800-1265AD) up to a quarter of the male population were of Scandinavian or North European origin.
The transition from Gaelic patronymic family names to hereditary names on the Isle of Man in the period ca 1050-1300AD has had unexpected genetic implications in that:-
a) There are examples of parallel name formation, namely different Y-DNA profiles with same family name
b) There is unexpected genetic persistence, in that we see the same male Y-DNA profiles, but possessed by families with different names
Kelly from the Isle of Man is really so!  All those familiar family names (e.g. Curphey, Bridson, Kennaugh etc) which we consider to be typical of and unique to the Isle of Man are shown to be indeed so.
Different variants of the same original Manx family name, which are popularly assumed to be equivalent, e.g. Callister and Collister, etc are indeed the same family.
Every one in eight men tested in the study did not show the genetic profile associated with the rest of his family.
The names of some early Manx emigrants changed/evolved after they left the Island in the 1700-1800s.
The close-relatedness of the Manx community genetically is a notable feature of the Isle of Man, as might be expected. Y-DNA testing indicates that a number of male lines are connected from early times. However autosomal DNA testing provides further  anecdotal evidence of this characteristic amongst a small population of people with Manx ancestry.

Manx Y-DNA Study Eight Year Progress Report

In order to make this report more easily readable and useable it has been divided into smaller sections as follows:-

Key Findings
Background & Characteristics of Manx Family Names
Y-DNA Testing and Methodology Used
Results Summary
The Future
Appendix I - Detailed Results for Each Family Name - updated 14th October 2019
Appendix II - Analysis and Interpretation of Results
Appendix III - Analysis of Non-Paternal Events
Summary table of results and progress  - updated 14th October 2019

Furthermore, an analysis has been recently carried out by Chris Keig examining the possible connection between a number of Manx families and the Viking Kings of Mann - see here


Those detailed results for each person tested through FTDNA can be seen here. More will be available in time, as will the analysis.  If your family name is incompletely tested or not all and you have a male candidate bearing your name and you wish to take part please feel free to contact me

The project continues to need financial support as well as further testing candidates. Each Y-37 test costs $150/100 and anyone can make a donation on line to the project here

I should stress that there is still a long way to go in time and effort before the precise early origins of these Manx male lines can be fully determined and so the project will continue for the foreseeable future. I will try and keep these above detailed results up to date as new information becomes available.
