Welcome to the web-site of the Clan Irwin Surname DNA Study.
This web-site, introduced a year ago, still within the main Clan Irwin Association (CIA) website www.clanirwin.org and supported by Rick Byers, has drawn favourable comments from both participants and third parties.
Highlights of this Update No.12 are:
- Steady growth continues. With over 270 participants with completed yDNA tests, our Study is one of the 60 largest of over 6,000 surname DNA projects.
- 25 distinct & mutually unrelated genetic families that use our surname have now been identified, most of which have been related back to a national or regional geographic origin.
- The 14 sub-groups within our large Borders genetic family identified a year ago still appear generally robust, although some minor revisons will become necessary as our understanding improves.
- SNP tests have shown that L555 does not help differentiate between our Borders sub-groups as had been hoped, but it is now included in the L-21 project, may be unique to our surname, and hopefully will in due course be included in the ISOGG phylogenetic tree and in FTDNA's Deep Clade Test.
- Most pages of the website have been updated and improved with minor amendments and clarifications.
- A new Supplementary Paper No. 7 has been added, to which is appended the Introduction to a recently published CD that contains much material that will be of interest to serious genealogists delving into the early history of the family, and in particular the early Irvings of Bonshaw.
