Welcome to the web-site of the Clan Irwin Surname DNA Study. This Study was launched in 2005, with the assistance of Kent Irvin, and the website was re-vamped in 2011 with the assistance of Rick Byers.  Both the Study and the website remain under the aegis of the Clan Irwin Association (CIA), although CIA is not accountable for the content of this website. 

This is Update No.20 of our Study.  Highlights include:
  • Growth of our Study continues, with 411 participants with yDNA STR results. 
  • In the past 6 months I have lectured on lessons learnt from our Study at FTDNA's 10th Annual Conference in Houston (November 2015)  (my slides as an update of Supplementary Paper 9) and, most of which I repeated at  "Who Do You Think You Are Live 2016" at Birmingham (April 2016).
  • We now have 25 participants who have undergone BigY tests, of which 16 are L555, i.e. members of our Borders genetic family. I have been able to undertake a BAM analysis of 13 of these.  More limited analyses of SNP data of another 5 L555 participants has been undertaken.  The implications of these analyses is still evolving. 
  • In April 2016 FTDNA launched their new L555 SNP Pack test, now available at $119 to L555 participants who have not taken the more expensive BigY tests.  This test is less powerful than the BigY test but tests for up to 100 SNPs younger than L555 - illustrative of the huge advances in this field.  36 participants took advantage of the introductory offer for this test.  The results are eagerly awaited.

PS  L555 Pack test results now coming in.  Analysis to follow shortly.  JMI 18 May 2016. 
PPS All members of our Borders L555 genetic family were contacted by e-mail on 18 or 19 September, and those who have not taken BigY or the new L555 Pack test are now encouraged to take the latter.  JMI 2 Oct. 2016.
PPPS  I am now updating many of these pages to incorporate SNPs into the main threads, and especially section 3.1 of "Latest Analysis Update".  There may be some internal inconsistencies until I complete my November update.   JMI 6 Oct. 2016.
