Short Update for Cooley Groups CF02 and CF09

Members of the CF02 group of the Cooley DNA Project, the "Tring Cooleys," have been doing advanced Y-SNP testing for about four years.1 The CF09 group, which is proving to be at least as diverse as CF02, has only recently started. I wrote about these tests earlier in the year in articles 48 and 58. Not much has changed recently except that a descendant of James Cooley (1758-1834) is individually testing the five novel SNPs discovered with kit B12855's recent Big Y. (The first tester is another Cooley/Gargus descendant.) Four of the five SNPs have been tested through Yseq.net. The reports from them are straight forward, as shown on the left. Each SNP name is listed followed by the allele value associated with that SNP and an indication as to whether the tester is negative or positive for that value. Using this information along with the knowledge that both testers' Most Recent Common Ancestors (MRCAs) were James Cooley and Penelope Gargus, a very simple tree can be constructed -- with the placement of A21961 (the fifth SNP) yet to be determined:

It's clear that all of the couple's patrilineal descendants (the father-line) will have the SNP A21494. We don't know, however, whether it came into the lineage at James's birth or with one of his immediate antecedents.

Haplogroup SK411, which I prefer to call A21489 because SK411 also exists on a very different branch of the global SNP tree, has a total of eight SNPs. There's some granularity to be found there, not to mention the three SNPs that belong to the Benjamin Coley tester, as well as the one found in the descendant of Washington Coley (see aforementioned Article 58 for more information).


It was once thought that all CF02 testers could have been descended from Benjamin Cooley (1615-1684). SNP testing has proved otherwise. Article 47, "The Re-Emergence of the Goshen Cooleys," details three individual lineages descended from the A12020 haplogroup, the Tring Cooleys, with two legs in the third. A long-awaited test shows a third leg in that third lineage. Indeed, it's long been believed that there were two Cooley groups, unrelated, in Goshen, New York. Recent DNA tests have suggested otherwise, and our newest Big Y test results, a descendant of Daniel Cooley (1688-1762), make them closely related -- DNA-wise, anyway.

There's fairly clear evidence, genetic and otherwise, that James M Cooley was descended from Jabez (1730-1808). Like the brothers Abe and Thad, he lived in Goshen before moving first to Kentucky, then to Ohio. It's been my assumption that he was the older brother of the three. The brothers left Goshen for Virginia. But having another match on all three Goshen SNPs makes it obviously that this was a much larger family than previously suspected. The relationship between Jabez and the brothers is no longer so apparent.

Daniel Cooley (1688-1762), another Goshen resident, was born of unknown parentage in Fairfield, Connecticut, the home of some of Samuell Coley's (1614-1684) descendants. An inference is easy to make. Advanced SNP testing for Samuell's descendants will indicate some extent to the degree of relationship there was between him and the Goshen Cooleys.

Abe and Thad's descendants have a tradition of birth in the British Isles (England and Ireland, respectively). The difficulty in tieing them genealogically to another family has made it tempting to believe that they, or their father, immigrated to the colonies. Daniel's much earlier colonial birth and the strong genetic connection now makes that less likely. However, we don't yet know when and what order the three A20351 SNPs came into the lineage. For now, the horizontal bars in the above graphic remain dashed.


Once again, it should be noted that, despite the efforts by some researchers, there's no genealogical tie between the CF09 Cooleys and the New England Cooleys belonging to CF02. However, there is a deep genetic connection. The first common haplogroup encountered, Y15926, is estimated to be nearly 3500 years old.

I keep track of CF02 SNP testing in Article 41. FTDNA has a great sale to the end of the year on the Big Y. I've just learned that a member of the CF10 group has ordered, which will be a big advance for them. Individual SNPs can be tested at Yseq.net for only $18 each ($15 until January 31, 2019). Now is the time for all good Cooleys to come to the aid of the project. (Paraphrased from Patrick Henry. I couldn't help myself.)

I'm always available for questions. Happy Holidays everyone.

1 At least two colonial Cooley families, Benjamin Cooley (1615-1684) and Samuell Coley (1614-1684), originated in Tring, Hertfordshire, England.
