Jim H.,
Thanks.
Were you SNP tested recently and confirmed as J1? It would be good to
know if you were or were not SNP tested!

Your haplotype is some distance away from the current modal haplotype
for J1. I have derived a modal haplotype for J1 from available
information (basically from: http://www.m410.net/yjdb). I did this
myself because of a lack of information regarding a J1 modal haplotype.
I list it below. Also, I am attempting to refine it with more markers
from data available on Ysearch.

J1 modal haplotype:
DYS394 =14 (you have 15)
DYS388 =16 (you have 13)
DYS390 =23 (you have 23)
DYS391 =10 (you have 10)
DYS392 =11 (you have 11)
DYS393 =12 (you have 12)
DYS389I=13 (you have 13)
DYS389b=17 (you have 17)
DYS426 =11 (you have 11)
DYS439 =11 (you have 13)
DYS461 =11 (you have 12)

You are a distance of 7 away from the above J1 modal haplotype of 11
markers and thus you are in the outskirts of the main distribution. J1
(M267) split from J-12f2.1 (M304) maybe 10-15000 years ago. Since then
random mutations to the Y-STR markers have been happening to the
ancestors of M267 (you too of course). It could be that since you are on
the outskirts of the current distribution (random being what it is) that
you slipped through without many mutations. But there are other
explanations. For example, if you got unlucky (unlucky meaning so as to
confuse things) and there were 3 fast (more recent) mutations in DYS388
and 2 fast (more recent) mutations in DYS439 then with out those "fast"
(more recent) mutations you would be much closer to the J1 modal
haplotype. Sometimes clear anwsers are difficult to find in our current
state of knowledge.

By the way, I think Di Giacomo's paper (2004) is a very good one, and
valuable publication. However, I just think he needed to use more Y-STR
markers (than the 5 he used) .

I hope others will jump in and add their observations.
