RESEARCH - preliminary outline
South Irish Project:
  • Donors that have been tested for 58 markers (multi-allele version of 67 markers) and a GD
    • less than or equal to 10 GD of the 58 marker South Irish and
    • less than or equal to 3 GD of Dr. Nordvedt's 12 marker South Irish
We're using a decision tree based on slow moving markers to find families based on their MRCA then adding the fast moving markers to identify branches (not sure how to handle the medium markers).  This information will then be applied when the unique South Irish SNP is found (and test donors take this SNP test) with adjustments made to testing criteria and conclusions as necessary.

Research Issue: We need to identify the slow and fast moving markers before starting to decide family trees and branches.  The FTDNA description of the slow and fast moving markers (see 12, 25, 37 and 67 markers) are in conflict with the ISOGG version of same.

Eoganacht Sept Project: We're starting with the Trinity Study in 2008.  I noticed that they used STR's to find out who the Eoganacht's may have been based on their DNA.  I believe the reason they couldn't come to a conclusion is precisely that they used STRs and did not identify the haplogroups of the test donors.  The documentation of the study (history of the Eoganachts) described their ancestry but the testing of the STRs reflected the current STR values of the test subjects.  A closer alignment would be to use deep ancestry DNA analysis (haplogroup analysis of the individual STR tests) to the deep ancestry goals of the 2008 Trinity Study; i.e. studying the deep ancestry of the Eoganachts.
 
I believe that by identifying the haplogroups of the test donors (see workbook columns AZ and BA, Best Match L-21 Project and Closest Match respectively) the study would have found the MRCA of the test donors which would have identified their ancestry.  This is the foundation of my study of the Eoganachts.  The study will eventually include those in the Normal Curve that are South Irish, possibly those that are Irish Type III, and those whose haplogroups may have been in the area prior to the time of the Eoganachts.  Those outside the Normal Curve will be explained before being eliminated or rethought as to belonging to the Eoganachts.
  • Identify the haplogroups of those that have a Eoganacht surname
    • if South Irish they are included, if not decide whether the test donor haplogroup:
      • existed prior to surnames (1000-1100 AD)
      • assimilated later (changed to Eoganacht names to be under the protection of the Eoganachts)
      • is Irish Type III
  • Identify the haplogroups of those who are South Irish but do not have a Eoganacht surname
    • Include as belonging to the Eoganachts
