SUMMARY OF YSNP (May, 2016)
Classification of Branch: Near Genealogical - son of FGC5660. Known sons: DC30 is the son of DC29. Estimated Breadth of branch (speculative estimate of positive submissions) = currently around foureen but scope will probably expand. Scope of Testing within Signature: Three Big Y tests, two FTDNA SNP packs and one YSEQ YSNP panel.. Dominant Surnames (including variants): O'Malley (3), O'Neill (2), Bryant (2), Davis (2), O'Laughlin (1), Hamilton (1), Harris (1), McNamara (1) and O'Hara (1) - many more could be added when true scope of branch becomes better known. Date that branch was discovered: Unknown. Source of Branch discovery: Three FTDNA Big Y tests (93878, 125443 and N104574). Number of Negative Broad Tests: Around 45 Big Y results and 30 more via packs & panels. Number of Negative Tests within Signature: None known. Pending Tests (within signature): None known.
ANALYSIS OF CURRENT DC29 HAPLOTREE I manually separated around 109 L226 submissions combined with 19 known YSNP results and used the SAPP tool to generate a chart which appears to be have extremely broad scope that was greatly reduced and evolution of YSTR had to significantly corrected. However, the SAPP did a very good job of identifying many close matches that were included in the haplotree. This branch of L226 has several issues preventing the complete descendant chart of DC29: 1) The six submissions that tested for DC29+ have one very strong branch that had pretty clear evolution of YSTR mutations, a second branch that reasonably well defined and a third small branch that is somewhat speculative but based on a fairly uncommon mutational value of 406S1. The scope of DC29 is very reasonable in scope but more than 50 % of the submissions that were predicted DC29+ were removed due to lack of much commonality with any tested submission. I basically kept the manual analysis but about doubled the size of the DC29 with the SAPP correctly identifying close matches to the DC29+ submissions. 2) The current limit of around 100 submissions limits the accuracy of the descendant chart for this particular L226 branch. As more submissions can be entered into the SAPP tool, as new branches discovered and as more YSNPs are tested, a several more submissions may be included under the DC29 branch over time. 3) However, between my manual analysis and the SAPP tool, eight good testing candidates were revealed..
OTHER FUTURE YSNP TESTING No pending tests are known.
DC29 Haplotree The link to the haplotree chart is the best way to look at the evolution of the DC29 haplotree. It is visually much easier to follow than spreadsheets and is very close to a genealogist descendant tree charts that genealogists already are well trained in analyzing:
Testing Candidate Recommendations This summary will attempt to priortize testing and explain why each test is beneficial to the the verification of the DC8 branch.
Here are the priorities for testing: 1) The scope of DC29 is fairly well known but its scope should increase some with more submissions allowed by the SAPP tool with more genetic information becoming available over time with more YSNP testing and new 67 marker submissions. 2) It is recommended that all current submissions that are predicted DC29 or DC30 positive should test both DC29 and DC30 for $35.00 from YSEQ. Current predicted DC29 positive and DC30 negative testing candidates include: DC29+ & DC30- predicted DC29+ & DC30+ predicted 3) Once these testing candidates are confirmed for their status of DC29 and DC30, testing the private YSNPs associated with their NGS submissions whose signature matches (in the same branch). These YSNPs will need to added to the YSEQ list of individual YSNP via the Wish a SNP request form (cost of $1 per YSNP). Once these YSNPs become avaialbe for testing, the first phase of testing would be: For those predicted DC29+ & DC30- AND 406S1=11 For those predicted DC29+ & DC30+ AND 460=12 None of these new YSNPs are currently available for order from FTDNA. However, if they do become available for order, one YSNP from FTDNA costs $39 or four YSNPs from YSEQ cost $70 which could discover a new branch vs. just testing a new branch that FTDNA has added.
