[[[[ With regard to other's databases given to me from other haplogroups,

according to their own criteria. But since you have no idea how I select my

One of these days I will just date the complete collection of every western
Europe M269 haplotype in sight --- with no further SNP or STR conditions
applied. When that turns out younger in age to its MRCA than you like, what
objection will you have then?
