The Tiernan DNA test


This is the very close test disappointingly, the Tiernan TN Group's best match was with the T Group with a 17 / 25 score and is less close with all the other groups.


All the test takers in the Tiernan DNA test as of February 5, 2005.
In process means they have the kit.  Pending means not yet decided to do the test

All eight separate MacTighernan DNA Groups, Kevin and James Patrick Tiernan and Philip O'Rorke fall into the larger DNA group called the Haplogroup R1b which is the most common haplogroup in European populations. It is believed to have expanded throughout Europe as humans re-colonized after the last glacial maximum 10-12 thousand years ago. The R1b lineage is also the haplogroup containing the Atlantic modal haplotype.

Kevin Tiernan 19344


























Below is the first pass at the web info on the Tiernan TN DNA study.  In order to make it easy to find a common ancestor, all the Tiernan ancestors below that were born in 1800 or close to that year are on the same line with a lighter color in the following chart. The symbol * by the names in the below chart denotes the emigrant not immigrant. The symbol "<" is an event that occurred before that year and a ">" is an event that occurred after that year, e.g. <1800 means born before 1800.


The below site has only 2 testers to date in the Tiernan DNA test.  One has completed the DNA test.  DNA kit numbers at the bottum of the below chart are in Italic, other numbers are YOB -YOD. 2nd last row is the tester's location at time of test.  Dawn at dsgroi4u2@centurytel.net is researching Anthony Tiernan.
