I gave it a try - the O'Doherty and O'Cain are somewhat near at around 40 (plus & minus 4 years) generation each, my attempt with 13 MacLoughlins results lead to conflicting values of 31 & 50.
Ewing and Cowan are somewhat possible, maybe around 20 generation. Certainly the common ancestor was not as old as the O'Doherty and O'Cain.
I like the idea of eliminating the questionable mutation rate by using it in both calculations and then comparing the results. My base halpotype for the O'Doherty and O'Cain had a GD of 2 out of 25 markers, hence offering the possibilty if surname ancestral bases are identitied for multiple families the process can be repeated again pushing back to the M222 ancestral base.
