L69.5 has tested positive for twelve 67 marker submissions: McGuire variants, Byrne, McCown variants, Corrigan and other surnames. Note: Only suspected or proven L513 positive submissions should test for L69.5 and P66 positive submissions (part of the deep clade test) should always test postive for L69.5. Also, consider that L69.5 may never get added to the ISOGG haplotree as L69 has five documented parallel mutations to date - this exceeds the maximum allowed of two parallel mutations. Since L69.5 qualifies for the genetic diversity rule, has around 100 testing candidates and has a son (P66) that is already included in the ISOGG haplotree, there is a reasonable chance for an exception to the parallel mutation qualification rule.

There are over 100 testing candidates for L69.5:

1) Within the Y-Search query and the R-L21 Plus 513-1113-A-2 submissions, there are over eighty good testing candidates that have not been tested that were higher than 70 % of the L69.5 fingerprint. Since this list is quite extensive, please refer to the L69.5 DNA Results spreadsheet for these testing candidates. Only the Burns Surname Project was extracted for possible testing candidates. The McGuire, McCown and Corrigan Surname projects could significantly increase the list of good testing candidates.

2) Within the Y-Search query and the R-L21 Plus 513-1113-A-2 submissions, there was around another twenty speculative testing candidates found that fall between 50 % and 70 % of the L69.5 fingerprint. See the DNA Results spreadsheet for those submissions that match only 6 and 7 of 12 markers of the L69.5 fingerprint. These testing candidates should be considered speculative in nature since very few submissions test positive below 70 % of SNP fingerprints and the only testing candidate that has tested in this range to date has tested negative (very small sample size to draw any conclusions of the breadth of the L69.5 SNP).
