Further on he presents a method to confirm a share common ancestor by comparing results from using the Poisson distribution of member's halpotype and a linear mutation method. They should come up with approximately the same number of generation.
Has this approach been applied for the populous surname projects - MacLoughlin, O'Docherty etc. ?
I understand that maximium halpotype is about 25 markers for the Poisson distribution, for we are looking for a common ancestor at around 30 generations.
If we get enough family ancestral bases then maybe we could then repeat the exerise and define an ancestral base for M222+ and date it.
