SUMMARY OF SNP

Current classification of SNP: Small sized branch. Note that L195 is currently a redundant Y-SNP of L144. Further testing of both Y-SNPs could later reveal a father-son relationship between these two YSNPs. Also note that L144 requires two fingerprints to cover all submissions. Currently four L144 positive submissions have also been tested positive for L195. For those submissions in the lower 20 % of the spreadsheet that are within 70 % of the L144 fingerprint, testing of L195 could determine a possible father - son relationship between L144 and L195.

Estimated Breadth of SNP: 30 to 40 submissions.

Dominant surnames testing positive (144-810): Whalen variants (4), Brazzel variants (3), Clark (1), McLaughlin (1), Phelan (1), and Prosser (1).

Dominant surnames testing positive (144-1399): Kendall (4).

Year that SNPs were discovered: 2009 (estimate).

Source of SNP: FTDNA - Unknown.

Number of Positive Tests (February, 2012): Twelve for 144-810 signature and four for 144-1399 signature.

Number of Negative Broad Tests (October, 2011): around 255
(since this is an older Y-SNP - most are from deep clade tests)

Number of Negative Tests within 70 % match of L144 fingerprint (144-810): None.

Number of Negative Tests within 70 % match of L144 fingerprint (144-1399): None.

Possible Candidates (70 % match) 144-810: Around fifteen.

Possible Candidates (70 % match) 144-1399: Around seven.

Pending Tests (within Fingerprint): Probably several from deep clade testing.

Note: This is a very mature and well researched Y-SNP that is fairly narrow. This Y-SNP is well researched due to extensive testing of this Y-SNP which has been around for quite some time. There are several very good testing candidates that still have not been tested but this is one of the most comprehensively tested Y-SNPs under R-L21.
