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.21 of our Study. Highlights include:
- Our Study now has over 420
participants with STR test results.
27 of these have ordered BigY tests, of which 17 Border Irwins have
their results, while over 50 Border Irwins have their results for the new L555 Pack
- Early results of the new Pack
tests have been fascinating; they reveal:
- the existence of more “sons” of L555;
- that our tentative sub-groupings on Border Irwins (BA, BD, B10 etc.) are
- our rapidly evolving L555 haplotree can now identify SNPs within our
known Border Irwin pedigrees.
- To reflect these major advances
the Study’s main Results table has been revised to incorporate SNPs and
the L555 haplotree.
- The text of the accompanying
webpages has been given a major review to better explain these exciting
- I was invited to give the
“Advanced” lecture at the Guild of One Name Studies’ Seminar on DNA at
Gloucester in September. An adapted
version of my PowerPoint presentation is now posted on line at
Supplementary Paper 9. Despite the title I
start at square one and participants who struggle with understanding DNA in general and
SNPs in particular may find this a useful learning tool.
- All Border Irwins who are not yet on the L555 haplotree (i.e. those numbered as items 75 through 277 on the accompanying Results table) are now
strongly recommended to take the L555 SNP Pack test if/when they consider
upgrading. For details see "Choosing further tests", section 3.2.
