Anatole,
Currently I have 69 of these J1 Cluster haplotypes (with DYS390=25,
DYS392=13, & DYS439=10).
I ran them through Ken's Generations2 program and the MRCA age came out
to 48.91436 generations or, using 30 years per generation, to 1467 years
ago. Very good! I knew about this cluster (once you reminded me :-)),
but I did not realize it was comprised of a good number of Jewish
haplotypes. Myself, I can not say it is a totally Jewish but it looks
like it is "quite a bit" Jewish! There are a large group of 10 marker
Ashkenazi Jews in this cluster from Behar's paper in (2004).
