I've done as you said. My father's brother's grandson tested and
came back J2 also. You can see the results at http://
There is a slight difference at 576 with one having a 16 and one a
17. FtDNA has the Haplogroups as J2e2 for my brother and just J2 for
my cousin. I don't know why they are not in the same Haplogroup. I
believe this confirms the relationship and the Haplogroup, even if my
cousin has not been SNP tested.
However, it still leaves open the question whether there would be a
difference between my untested brother born in 1933 and my untested
brother who was born in 1963. When I can afford it, I will try to
convince them to let me have their Y-DNA tested.
I'm just a curious person.
