The SNP Descendency Tree (aka the "Haplotree") for the R-Lindsays.

An excellent read is a book by Alistair Moffat entitled The Scots: A Genetic Journey. It gives an anthropoligical backdrop for understanding our collection of genetic “signatures”.  More than half of our genetic families are R1b Lindsays, who are, more specifically, R-M269>L23>L51>P310>L151.  Drawing here on Moffat, with oversimplification for the sake of brevity, the agricultural revolution in the Fertile Crescent resulted in a population boom that found relief in westward migration into Europe after 6000 BC. Indo-European speaking peoples spread over centuries and millenia and the R-M269 haplogroups came to dominate Europe, including the British Isles and Scotland. (“R”, think “Recent”–post Ice-age, or faRmeRs… cf I-Lindsay Haplotree)  70% of Scottish men are descended from this transformational migration, as are 110 million men of continental Europe.  This transformation of Britain and Ireland was gradual.  Attempts can be made to map the various subbranches of of R-M269 onto the Celtic linguistic populations of the Picts, the Welsh-Britons, who probably came across the North Sea, and later the Irish-Scotti, who probably came up the Atlantic coast of France from Spain. Since R-M269 dominates Scotland and Ireland, it should not be surprising that it dominates the Lindsay Project numerically.

The placement on the haplotree of Group 13 can only be known through advanced SNP testing.  Group 04’s coarse placement is known from a deep clade test taken six years ago.  The Big-Y would locate it to a greater degree of precision.  Group 23 was placed coarsely in this update thanks to their first Big-Y.  A second member has ordered theirs and a considerable refinement of placement is anticipated.
