The only surnames currently testing positive for these Y-SNPs are the surnames Hopkins and Greaves. With the recent discovery that L319.1 is the father of L302, L319.1 should always be tested prior to L302. For very high fingerprint matches (above 70 %), both SNPs should now be tested. With the recent addition of another marker to the L319.1 fingerprint, expanded testing results now available, discovery of FTDNA IDs associated with several key submissions and many untested McCabe submissions, testing recommendations have changed:
1) Since L319.1 is now known to be the father of L302, two very key submissions need to be tested for L319.1: Gillespie (188270) and McCabe (127552).
2) Higher fingerprint matches with non-McCabe surnames, should be high priority for testing: Byrne (134461), Sutphin (9DK5D), Searcy (146133), Harrison (M56X4) and Ball (13455).
3) Since McCabe submissions at 100% fingerprint matches have not been tested for L319.2, continued testing of McCabe submissions should continue (only at 100 % matches) for now. Only submissions with different oldest proven common ancestors should be tested which will probably eliminate most of the McCabe submissions. Testing candidate should come from the following pool of McCabe testing candidates: 139946, 146567, 176320, 168113, N36342, 1106, 825, 826, 827, 127552, 147989 and 54231.
4) There are two submissions where testing results can not be confirmed via FTDNA Y-SNP reports. It is doubtful that ISOGG would accept these submissions that can not be confirmed via established FTDNA Y-SNP reports. Hopkins submission 183161 is available for review via FTDNA Y-SNP report but does not show any testing of L312.1 or L302. It is rececommended that the sponsor of this test request FTDNA to manually add these SNP testing results or these SNPs should be tested by traditional tests. The Greaves submission only has the Y-Search ID available and no report has been found to confirm the Y-SNP test results. It is highly recommended that the FTDNA ID of the Greaves submission be documented and that this submission joins the L21 project or some other project so that the Y-SNP testing can be verified. It appears that L319.1 could qualify for the ISOGG haplotree in the near future since GD = 8 has already been confirmed.
5) L319.1 positive submissions should at least test all major older and broader Y-SNPs to determine L319.1's position relative to other L21 Y-SNP. It is highly recommended that L319.1 positive submissions test for the following broad Y-SNPs: DF21, Z255 and DF49. It is also recommended that other ISOGG testing requirements be tested in preparation for ISOGG qualification. With extensive testing, L319.1 could eventully qualify for the ISOGG haplotree. Testing funds should concentrate on testing both L319.1 and L302 at 10 of 10 marker matches along with a few non-McCabe submissions with 9 of 9 matches.
Due to several well-planned tests that has resulted in negative Y-SNP results at higher fingerprint matches, these Y-SNPs are quickly becoming a very small branch that is "near private" at the best. If some of these tests provide positive results, continued testing would then be warranted on a limited basis. With the discovery that L319.1 is the father of L302, only L319.1 should be tested alone for any future testing. For 9 of 10 or higher matches, both L319.1 and L302 should be tested.
