McCorkle Surname DNA Project

Test Results

We currently have 6 participants.

Last update: 28-Jan-2008 11:45 AM

Of our 6 participants so far, we have two with 37 markers (kits 42234 and 73251), two National Geographic Genome Project participants with 12 markers (kit N12220 and N49855), and two with 25 markers (kits 43653 and 43663).

It's clear that we have four closely related individuals from only one distinct family group. Kits 42234 and 43653 are documented back to their common ancestor, John McCorkle, b. 03 Aug 1734. These two participants match kit 43663 at 24/25 markers (DYS 464d is 18 vs. 17). It would be most helpful if participant 43663 provided his lineage to his earliest known ancestor so we can pinpoint the location of the mutation at marker DYS 464d.

The additional row (YSearch.org) is from an entry discovered in the Ysearch.org database in 2005, although that entry is no longer available. This person is ostensibly in the FTDNA database, but thus far has not joined this project. To date, no info is available about this person's earliest known McCorkle (MacCorkle) ancestor or his descendants.

Note the top line in the table is the Western Atlantic Modal Haplotype (or WAMH). This is provided as reference since FTDNA points out that our current participants, who all match at 12 markers, are only 1 point away from the WAMH (DYS 391 = 10 allels for Group 1, vs. 11 allels for the WAMH). The WAMH is the most common Y-DNA signature of Europe's most common Haplogroup, R1b. That means, for research purposes, the 12 marker test is only minimally useful, at least in terms of identifying divergent lines of related individuals. In fact, the 12 marker McCorkle results match 281 other FTDNA customers, none of which have surname McCorkle or any of its variants. The conclusion, then, is that for this particular clan, at least 25-marker tests will be necessary to make any meaningful analysis or comparison of results.

Notice, for our only family group so far, it has the following modal marker values: 391 = 10, 458 = 18, 449 = 30, 464a = 13, and 464c = 16. These values are different from the WAMH, for which these four markers have values 17, 29, 15, and 17, respectively. Of special interest, DYS 464a = 13 for only 2% of individuals identified as having the R1b haplotype. Thus, DYS 464a is distinctive in identifying members of this clan of McCorkles.
