(It was base haplotype C, with 9 mutations off compared to the AMH, hence, ROUGHLY 249 generations = 6,225 years to a common ancestor of "C", see my preceding message).
If so, considering that the AMH is 160 generations = 4000 years "old", a common ancestor of Irish Type III AND the AMH lived
(1100 + 4000 + 6225)/2 = (tentatively) 5,700 years BP. It is "tentatively" until it is confirmed that the mutational difference between the ITIII and AMH is 9 mutations (in 25 markers) indeed. If it happens, say, actually 7 mutations, that 5,700 years moves to a rather ordinary (still on a high side for Europe) 4,850 years.
