Part 880sr – Smith Robertson Genealogy – Updated Y-DNA Results – Haplogroup R-CTS7822

27 August 2014

Good Day,

I have been reclassified. My Smith Paternal Line is R-CTS7822.

This means that as a descendant of ggg-grandfather James Smith my Y-DNA has gone from one of the more-common to just a little less-more-common… And this includes all male descendants of this Smith line, including the Lloyd Smiths, the Malin Smiths, the Landreth Smiths, et al, that is, if you can trace your ancestry back to great-great-great James Smith of Grenada.

Most recently I had two more SNPs tested – CTS7822 and F2863 with Family Tree DNA. That’s Single Nucleotide Polymorphism, SNP, pronounced snip; plural snips. SNPs are the most common type of genetic variation among people.

One test, F2863 came back negative and the other, CTS7822 came back positive. My Haplogroup classification at Family Tree DNA and at National Geographic’s The Genographic Project has now been changed to R-CTS7822. This is an adjustment from the previous R-L23 and this has something to do with the mapping of the YSC0000072, even though Family Tree DNA has me tested as negative for this SNP.

And what does this mean? According to Geno 2.0 of The Genographic Project each person is assigned to a specific Haplogroup. The Haplogroup is my branch on the human family tree… People belonging to the same Haplogroup can trace their descent to a common ancestor and even a specific place where that ancestor may have lived.

I am 1 of 678,632 participants of The Genographic Project. Accordingly 0.8% of all participants in the Project are included in my paternal Haplogroup and that includes 5,429 participants. As the Y-DNA is passed from father to son to son this means, once again, that all of ggg-grandfather James Smith’s descendants are of the R-CTS7822 Paternal Line.

As a member of one of the Y-DNA projects, the Bristol Channel DNA Project, the current update includes the following members with the Surnames which have tested positive for the SNP CTS78222.  These include Bennett, Coat, Follis, French, Locke, Peed, Robinson, Seymour, and Smith.

One of the project members has been running an analysis on our STRs (Short Tandem Repeats) and has calculated/estimated that our MRCA (Most Recent Common Ancestor) for our grouping may have lived somewhere between 950 AD and 1200 AD. This time frame may be subject to refinement as more kits (albeit persons) join this specific Project.

There is still one hell of a lot that I need to learn and understand. I’m a bit farther along, but I have only scratched the surface of the information. Images and certificates are published by Family Tree DNA and National Geographic The Genographic Project.

Stay tuned.

And the mosquitoes are biting tonight. Have to get me some bay-rum for the itch.

I would call CTS7822 as extremely rare and mysterious,
