News for G2a3b1a2a1 persons

Because your L42 subgroup is relatively small, you must rely on the overall mother group for L42 for most news.  The mother group is L497.  

Within the 1000 Genomes Project last fall I was able to extract perhaps about 100 SNP mutations found in five L497 men.  Some of these are SNPs shared by all L497 men.  There were an unusual number of these. suggesting that the L497 group existed as a small group for perhaps a millennium or more before a big expansion began.   Within all these SNPs are probably 10 to 20 that represent valid branches of the L497 subgroup.   We would like to have all of these available for testing, but Family Tree DNA will only provide tests that meet multiple criteria, and we were only able to get tests for Z725 and Z1901which likely only represent fairly small L497 subgroups.  We will continue to try to see that promising SNPs in this resource would be turned into tests.  If we can get these new SNPs as tests it will really accelerate progress in defining the movements of your L497 ancestors.

 L497 samples outside of Europe continue to be almost unheard of.   We  were particularly interested last year in a sample from the island of Lemnos off the western coast of Turkey. This island has known connections to the Etruscans.  This sample did turn out to be L497+ though it has some very eccentric marker values.  And a researcher found a sample with similar marker values from the west coast of Turkey that is also L497 -- the only Turkish sample of this category in his collection.  The question remains open whether whether these men are from an early branch of L497.  If so, this could argue for an early movement from the Turkish coast to Europe in conjunction with the Etruscans.

This year we added a new feature to the G web site that deals with the L497 subgroup.  
The purpose was to estimate the number of L497 men as a percentage in the population based on marker values.  This is an imperfect way to do this, but many of these sites do not have L497 testing, and this is the best we can do in the meantime.

In addition to all this, it must be pointed out that there is one L42 man in the 1000 Genomes Project.  I found perhaps 15-20 SNPs that were specific to this L42 man and not share by other L497 men.   Included within these SNPs in the L42 man are likely SNPs that show branching within L42 men.  We will be looking for ways to have these SNPs tested.
We will do some targeted testing on L42 men last year to try to refine the prediction criteria for being a L42 man.  Co-administrator Rolf Langland has a special interest in the L42 group because he is confirmed L42, especially why this is found among some Norwegians.  He makes the final decision as to who should be predicted as L42.  It is possible that both the L42 subgroups shown were added in the last 12 months.  Both have some dramatic marker values not shared by anyone else.  At this point we are continuing to evaluate a SNP found in the L42+ Paver/Pever men (L297) to see if it has coverage beyond that family.  If any one of you wants to test for this, your additional results would be welcome.  But we are listing it is private until some different result is obtained.

We have divided your L42 (G2a3b1a2a) subgroup  into three categories.
(1) Those confirmed L42 and negative for  L42 subgroups.
(2) Those confirmed L42 but not tested for all subgroups
(3) Those only predicted L42.

There is nothing more that the men confirmed negative for L42's subgroups can test.  We will continue to look for ways to further subdivide you.

Those not tested for the L42 subgroups, in most cases, this involves testing for a single marker for $7.20 -- a bargain.  I will be glad to discuss this individually.  However, Mr. Myers would almost certainly have the same results as the Myers already tested.

For those in the predicted L42 category, we are only about 85-90% certain you are L42.  Confirmatory L42 testing for $29 is sorely needed to confirm your status.  Only one person within a surname project needs to test for SNPs. All will have the same results.  

As mentioned in the general news section, if you are willing to better define your grouping, I will be glad to give individual recommendations and help. rayhbanks@cox.net.
