OK. Exactly what am I looking at in these numbers? GD's against a
group modal or GD's when individual samples are compared?

Here's the distribution for the Doherty samples (GD's against the group
modal).

1 (8)
2 (9)
3 (12)
4 (8)
5 (10)
6 (5)
7 (3)
8 (1)
9 (2)
10 (1)

These are the numbers in your file:

1 0 0.00000 0.00000
2 71 0.03029 0.03029
3 183 0.07807 0.10836
4 323 0.13780 0.24616
5 500 0.21331 0.45947
6 525 0.22398 0.68345
7 376 0.16041 0.84386
8 249 0.10623 0.95009
9 91 0.03882 0.98891
10 19 0.00811 0.99702
11 5 0.00213 0.99915
12 2 0.00085 1.00000

What has me confused are some GD's between individual Dohertys. One
sample (the one at 10 against the group modal) comes in at a GD of 15
and 16 against two other Doherty samples. That's an extreme example.
Most are no where near that far apart. Despite the surname he doesn't
match the Doherty modal well (0 of 4). He is M222 though. Maybe this
isn't really a Doherty but some kind of M222 NPE. There were enough in
that part of Ireland.
