About us

Our preliminary analysis of Y-DNA results showed two major groupings with a number of smaller groups, some of which fall between the two large groups, potentially forming a mutation bridge some time ago. Nothing has caused us to change this analysis
In 2015 we updated the analysis based on Generations to Most Recent Common Ancestor for those participants who have taken 37, 67  and 111 marker tests; the page shows all results in one list, regardless of the number of markers tested.The results at were current at July 2018 and will not be updated

In a relatively few cases it seems that some of us may have gained our name through our mother, or less likely, through adoption. In other cases the signatures appear to be solitary but close (several generations) to one or more of the groups. In this case we most likely do not have enough participants yet. Gratifyingly some have joined the project with derivatives of our name and shown a definite link e.g. Agin, while others have not yet been able to show such a link.

How to run the TMRCA analysis for yourself

  • Log in to your FTDNA page
  • in a separate window, load this Public website and look at the Classic results page
  • in a third window open the McGee Y-Utility: Y-DNA Comparison Utility, FTDNA 111
  • select all the results on the Classic results page, excluding the header row, and copy - don't forget to scroll right across to pick up the 111 markers
  • paste the selected data into the box at the bottom of the McGee Y-utility page
  • click Execute
A separate window with the analysis will open. The data is presented in the same order as on the Results page, but identified only by kit no. If you scroll down past the marker data and across you will see blocks of matches with numbers representing generations to most recent common ancestor in coloured squares. Towards the bottom of the results you will see an explanation of the colours used, and the settings used in the analysis, for example the diagonal row shows the number of markers present for that kit. You can change the settings and re-execute the script

As time permits, we will create new groups to reposition participants and attempt to bring those who match closely together
