What's New

I have run a new calculation of the age of our cluster using a set of 181 37-marker haplotypes and a second set of 81 67-marker haplotypes.

These result is 993 years and 966 years respectively ... certainly about the time of Brian Boru!

A further run omitting the variable markers, 385, 389, 459, 464 and CDY resulted in a time of 1086 years with an error of ±20%.
