Most Distant Positive Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

None - only one tested.

Closest Negative Test Known (67 markers)
(from MRCA of positive submissions - not WTY):

McDaniel, FTDNA ID 36483, Y-Search XZZZR, only 5 of 13 fingerprint match and GD = 13.

DNA Signature (Walsh): None Found.

Note: There are no proven positive tests for this Y-SNP. According to post in the Genealogy DNA forum (Rootsweb) by Thomas Krahn in June, 2009: "L130 is certainly very rare in R-L21. I would only recommend this marker for group 54 in the Campbell project so far."
