Thu, 17 Jan 2008 00:38:08 EST  The Trinity Study.  The Trinity
study, based on a sample of 59 surnames linked by pedigree to
Nial 'of the Nine Hostages' (d. 405 A.D. ), arrived at two
different TMRCA estimates; one was 1730 years ago, or about 277
A.D. The second estimate was 1,010 years ago (or about 997
A.D.). The team concluded the first estimate was "at least
consistent with an early medieval time frame." The second
suggested an origin predating the adoption of surnames in
Ireland (generally beween 950 A.D. and 1100 or later). Of these
59 samples roughly half matched the IMH modal or what is now
called R1b1c7. The Trinity team suggested the non matching
samples were the result of "the cumulative consequence of
nonpaternity events and the induction into the clan structure of
unrelated males. "  The Following surnames were involved in the
59 sample study.  (O’)Gallagher (12), (O’)Boyle (9)
