SUMMARY OF SNP

Classification of SNP: Medium sized branch.

Estimated Breadth of SNP: 20 to 30 submissions.

Scope of Testing within Fingerprint: (October, 2011) - 11 from Y-Search by haplogroup.

Dominant Surnames: Whalen variants (7), Brazzel variants (5), Phelan (2), Clark, McDonald, Cook, Durie, Barton and Prosser.

Year that SNPs were discovered: 2009 (estimate).

Source of SNP: FTDNA - Unknown.

Baseline for SNP: Multiple submissions that have tested positive.

Number of Positive Tests (October, 2011): Around 14 (Y-Search by haplogroup & Walsh).

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 Fingerprint: None.

Possible Candidates (70 % match): Around 20.

Pending Tests (within Fingerprint): None known.

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.
