SUMMARY OF YSNP (May, 2016)

Defintion of FGC5659 STAR: FGC5659 STAR equates to FGC5659 positive and negative for all sons of FGC5659. For FGC5659, there are currently five sons: DC1, DC36. DC38, FGC5647 and DC41. Therefore, this branch includes only submissions that are FGC5659 positive and negative for the five sons of FGC5659. Only NGS tests can be truly FGC5659 STAR as FGC5647 is not tested by the FTDNA SNP pack test (but its scope is very genetically isolated).

Classification of Branch: Probably the third largest branch under L226 after FGC5660 and FGC5628.

Known sons: DC1, DC36, DC38, DC41 and FGC5647 are sons of FGC5659.

Estimated Breadth of branch (speculative estimate of positive submissions): currently only around seventeen submissions but the true scope is probably at least twice as large. Due to the 100 submission limit of the SAPP tool, the older age of this branch, less divergence found in this branch, massive parallel mutations under this branch and belonging to the bottleneck trunk of L226 where 30 % of all L226 private YSNPs reside, this branch will remain one of the most challenging branches to accurately and fully chart.

Scope of Testing within Signature: Three Big Y tests (67 markers), four FTDNA SNP pack tests and three YSEQ SNP panel tests.

Dominant Surnames (including variants): Carey (4), O'Brien (3), Kennedy (2), Dunphy (1), Goodhind (1), Hartary (1), McMahon (1), O'Donoghue (1), O'Shea (1) and Sheill (1).

Date that branch was discovered: Unknown.

Source of Branch discovery: Three FTDNA Big Y tests (293008, 164407 and 176989).

Number of Negative Broad Tests: Around 45 Big Y results and around 40 more via SNP pack & SNP panel tests.

Number of Negative Tests within Signature: None known.

Pending Tests (within signature): None known.

ANALYSIS OF CURRENT FGC5659 STAR HAPLOTREE

I manually separated around 120 L226 submissions combined with 40 known YSNP results and then used the SAPP tool to generate a chart which matched my manual analysis (after some modest re-arrangement of YSTR based branches). The SAPP tool appears to have missed connecting several submissions under common mutations but these connections are not extremely strong either. Both my manual analysis and the SAPP tool (with 100 submission limit) failed to reveal many submissions that probably belong to this branch. There is just too little divergence from the L226 modal to have enough genetic information connect many of the submissions that are probably part of this branch.

1) Since there were nine YSNP tested submissions to analyze (worthy of being declared FGC5659 STAR), I first looked at the signatures of these submissions and manually determined several possible common YSTR marker mutations. The SAPP did not do a very good job with all the branching information due to the lack of divergence from the L226 modal. Also, there is also massive convergence of submissions due to significant parallel and backwards mutations. The true scope of scope of FGC5659 STAR is probably at least twice as large that what my manual analysis or SAPP tool can currently find.

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 are discovered and as more YSNPs are tested, many more submissions will be included under the FGC5659 STAR branch over time.

3) However, between my manual analysis and the SAPP tool, seven good testing candidates were revealed. Increasing the SAPP limit of 100 submissions may help some but the lack of common shared mutations and the abundance of parallel mutations between submissions will remain a significant obstable in producing a complete and accurate descendant chart under FGC5659.

OTHER FUTURE YSNP TESTING

No pending tests are known.

FGC5659 STAR Haplotree

The link to the haplotree chart is the best way to look at the evolution of the FGC5659 STAR haplotree. It is visually much easier to follow than spreadsheets and is very close to genealogist's descendant tree charts that genealogists already are well trained in analyzing:

Haplotree of FGC5659 STAR

This summary will attempt to priortize testing and explain why each test is beneficial to the the verification of the FGC5659 STAR branch.

Here are the priorities for testing:

It is not recommended that any of current submissions that are predicted positive for the FGC5659 STAR should test the individual YSNPs of FGC5659, DC1, DC36, DC38, FGC5647 and DC41. Rather than test six YSNPs at $105.00 from YSEQ, it would be preferable to order the YSEQ SNP panel test for $88 which includes eight branches under FGC5659. It is not recommended that these testing candidates order the FTDNA SNP pack since this test tests only six branches under FGC5659 for $119.

1) Since one submission has already tested for most branches under FGC5659, it recommended that this submission only test for the missing three YSNPs:

Carey 315758 - test for FGC5659, FGC5647 and DC41 only.

2) Their are very strong signatures associated with some parts of FGC5659 STAR and it is highly recommended that these submisisons should order the YSEQ Z253 SNP panel test:

Sheill 44001
Dunphy 154629

3) There are also two other signatures that are fairly strong and it is recommended that these FGC5659 STAR submissions should order the YSEQ Z253 SNP panel test:

Hartary 74708
O'Shea 242801

4) There are also three other signatures that are fairly strong and appear to be part of small surname clusters. It would be useful (but not critical) that these FGC5659 STAR submissions should order the YSEQ Z253 SNP panel test:

Carey 112620
Carey 132875
Kennedy 273590

5a) After the above testing verifies that you do belong to the FGC5659 STAR branch, a few submissions should test the private YSNPs of NGS submissions that belong to the same branch. Only one testing candidate qualifies for this testing:

Dunphy 154629

The first step is to order a "Wish a SNP" for four private YSNPs at $1 each. Once these YSNPs become available for order, then they should test these private YSNPs:

DC16, CTS8976, DC269 and DC270 ($70)

If Dunphy tests positive for just one private YSNPs, a new L226 will be discovered.

5b) After the above testing verifies that you do belong to the FGC5659 STAR branch, a few submissions should test the private YSNPs of NGS submissions that belong to the same branch. Only one testing candidate qualifies for this testing:

Hartary 74708

The first step is to order a "Wish a SNP" for four private YSNPs at $1 each. Once these YSNPs become available for order, then they should test these private YSNPs:

DC283, DC284, DC285 and DC286 ($70)

If Dunphy tests positive for just one private YSNPs, a new L226 will be discovered. After these tests are completed, three additional private YSNPs should be tested (or all seven could be ordered at once as well):

DC287, DC288 and DC289 ($52.50)

6) There are two submissions that have significant YSNP testing but are only 37 markers. Since this web site is dedicated to determining signatures associated with 67 marker submssions, these two submissions are not included in this analysis. It is highly recommended that these two submissions upgrade to 67 markers:

Gibson 294619
Collins 152324
