As derived SNP L1253+ (currently assumed to be just 550 years old) is turning out to be very significant for this British Isles cohort of J1 testers, it was thought best to make it a distinct public website, enabling a more focussed approach to it's research potential.  Most of what follows, employs data from the BigY test results for, inter alia, our member's kit no. 59183 and from the Victar Mas (J1 Project) Phylogenetic Tree (Issue 133), now requiring updating.  See ''About this Group'' Results Tab.
