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

Key headline findings from the study so far are:-

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.
Unexpectedly, a number of male Manx lines with different family names were found to be related and share common male ancestors in the period before hereditary family name adoption.
The unique Y-DNA signatures of more than 70 (out of 125) Manx family lines have been identified and knowledge about their early origins gained.
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.
Most Manx families show a single male genetic origin, as would be expected of such small families.
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 5 Year Progress Report - published 31 Dec 2015 - Updated 7th Jan 2016

Please note that as a result of feedback following the issue of these documents a number of key corrections have been made in the analysis and text after the identification of several wrong assumptions on the author's part. The most obvious sign of that is that the Scandinavian origin percentage has reduced to 25% from 33%. Apologies for any confusion this might cause - JAC

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

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.
