Lots of stuff to chew on here!
Yes, 88646 doesn't get any closer than GD 3 (with 65678), GD 4 with
180243, and GD 5 with the remaining two lines. This man comes from the
only one of the five lines that remained on Prince Edward Island. The
progenitor of this line is thought to be the brother of the progenitor
of 65678 (but I have some doubts about that). Many of these people had
the same first names, and I think the paper trail may be incorrect--the
name of the brother is correct, but they may have a different person
with the same name assigned. The 88644 line (my first cousin) isn't any
closer than GD 4 (to 119699) and goes up to GD 6 with 88646. I'm using
67-marker values here though. My cousin (88644) has the only mutation
in the 38-67 area. It's a one-step mutation at DYS 534. He is a 15, the
others are 16. 88646 has several differences from the rest: 16 at DYS
464c while the rest are all 17. It is not a recLOH. I had 464X done on
them all. He is 11 at DYS 460, the others are 12. At DYS 458 he and
65678 have 18, the rest 17. So differences like this seem to send people
to one end or the other. I'm kind of surprised that 88644 is closer to
the rest of them on the chart than is 88646.
It'll be interesting to see how the 111 results will help clarify
things. Kits 88644, 119699, and 65678 lived between 1-2 miles apart in
Cape Breton for many, many years.
