I don't know how others would interpret this but the main cluster of the group appears to come in at between 4-6 GDs against the M222 modal. This group includes several large surname groups (Doherty, Ewing and McLaughlin) plus some smaller ones (Dunbar, McCord, Cowan, Duncan) and a lot of singletons. , , ,



If the surnames are ignored and the skewing is assumed to be from an insufficient sample, this looks very much like a normal distribution curve. That in itself means nothing in itself: a hypotheses could be examined with the data, but a hypothesis can't be created from the data. A it stands, it is only a correlation between two sets of numbers. An example: years ago, I read an article that demonstrated a very good correlation of the sales of cigarette lighter fuel and the incidence of lung cancer. The article was an argument against using statistics to determine public policy and was not intended to show causality.
